SUMMARY:MSE Seminar: Fang Liu
DESCRIPTION:Event interval: Single day eventAccessibility Contact: Matthew Yankowitz\, myank@uw.eduEvent Types: Lectures/Seminars \nTitle: Fang Liu\, Michigan Technological University\, will present "Large scale production of artificial two-dimensional superlattices." \nAbstract: Two-dimensional (2D) materials and their engineered lattices offer exciting opportunities for next-generation electronic\, optoelectronic\, and electrochemical devices. Yet\, studies of high-quality heterostructures have been largely constrained to microscopic flakes. Here\, we present scalable\, controllable top-down methods that transform a wide range of van der Waals (vdW) single crystals into twisted moiré superlattices with high yield\, exceptional uniformity\, and macroscopic dimensions from millimeters to centimeters. Access to such large-area structures has enabled new discoveries\, including ultrafast thermal exchange at bilayer interfaces\, rapid photoinduced tuning of moiré patterns\, and markedly reduced Debye temperatures in deformed monolayers compared to their isolated counterparts. Furthermore\, by patterning 1D features—such as nanoribbon arrays and nanowrinkles—on 2D monolayers\, we uncover unique electronic and thermodynamic behaviors absent in pristine layers. These advances in large-scale 2D artificial structures pave the way toward mass production and practical deployment of twistronic devices. \nBio: Dr. Fang Liu is an Assistant Professor of Chemistry at Stanford University. She started her group in 2020. Her research focuses on the light-induced dynamics of solid low dimensional materials and construction of low dimensional artificial structures. Prior to her current position\, she was a postdoctoral fellow in the group of Prof. Xiaoyang Zhu at Columbia University. Prior to working in Columbia\, she worked under the direction of Prof. Marsha I Lester at University of Pennsylvania. She received her Ph.D. in 2015 and worked as a postdoc in the same group in 2016. She received her B.S. in chemistry at Peking University in 2010.

SUMMARY:Towards reconfigurable and deterministic twistronic 2D materials
DESCRIPTION:Speaker: Yuan Cao\, University of California at Berkeley\nTwo-dimensional materials (2DM) and their heterostructures offer tunable electrical and optical properties\, primarily modifiable through electrostatic gating and twisting. While electrostatic gating is a well-established method for manipulating 2DM\, achieving real-time control over interfacial properties remains a frontier in exploring 2DM physics and advanced quantum device technology. Current methods\, often reliant on scanning microscopes\, are limited in their application scope\, lacking the accessibility and scalability of electrostatic gating at the device level. In the first half of this seminar\, I will introduce an on-chip platform for 2DM with in situ adjustable interfacial properties\, employing a microelectromechanical system (MEMS). This platform comprises compact\, precise\, and versatile devices capable of voltage-controlled manipulation of 2DM\, including approaching\, twisting\, and pressurizing actions. We demonstrate this technology by creating synthetic topological singularities in the nonlinear optical susceptibility of twisted hexagonal boron nitride (h-BN).In the second half of this seminar\, I will talk about our recent progress in observing symmetry-forbidden second-harmonic generation in almost any 2D crystals\, which is extremely useful for deterministic twistronics. Optical spectroscopy based on second-order nonlinearity is a critical technique for characterizing two-dimensional (2D) crystals\, and it also finds numerous applications in bioimaging and quantum optics. It has been generally believed that second-harmonic generation (SHG) in crystals with inversion centers (centrosymmetric crystals)\, such as graphene and other bilayer 2D crystals\, is negligible without externally breaking the symmetry via strong surface effects. However\, with a new ultra-sensitive detection technique\, we could circumvent the symmetry-imposed constraint and observe robust SHG in pristine centrosymmetric crystals\, even without any symmetry-breaking field. With the exceptional sensitivity\, we directly observe polarization-resolved SHG in bilayer hexagonal boron nitride (h-BN)\, bilayer WSe2\, and remarkably\, Bernal-stacked bilayer graphene\, allowing us to unambiguously identify the crystallographic orientation in all these crystals via SHG. We also demonstrate that the new technique can be used to non-invasively detect uniaxial strain and geometric phase in these centrosymmetric crystals.

SUMMARY:Alioscia Hamma (University of Naples Federico II): Why is Magic Important (in Holography)
DESCRIPTION:In recent years\, the notion of magic in quantum physics – originally confined to more esoteric quantum information processing subfields – has attracted the attention of the community of quantum many-body physics\, quantum chaos and complexity\, high-energy physics\, AdS-CFT and the foundations of quantum mechanics. In this talk\, I will show why and how quantum magic matters to holography\, how it describes gravitational back-reaction\, and set up a program of entanglement-magic duality.

SUMMARY:Bo Peng (Pacific Northwest National Laboratory)\, QISE Seminar: When Quantum Systems Remember: Fractional Open-System Dynamics via Random Time
DESCRIPTION:Abstract: Real quantum systems are never perfectly isolated: coupling to an environment causes relaxation and decoherence. The standard “memoryless” (Markovian) description—Lindblad dynamics—often predicts simple exponential decay. Yet in many physical settings\, environmental correlations persist\, producing memory effects and non-exponential relaxation. The key question is not whether history matters\, but how memory decays in time. In this talk\, I will introduce a fractional-calculus framework that organizes unitary dynamics\, Markovian master equations\, and long-memory non-Markovian behavior within a single hierarchy. The central idea is “selective memory”: long-time behavior is often governed by a small subset of slowly decaying correlations rather than the full microscopic history. Technically\, fractional dynamics can be understood as standard Lindblad evolution running under a randomized clock (Bochner–Phillips subordination)\, which preserves physical consistency (complete positivity) while generating algebraic long-time tails. I will illustrate how memory alters the shape of relaxation—not just the decay rate—using simple qubit examples and published benchmarks\, and I will briefly discuss how the same structure would enable scalable simulation without explicit time-history storage. \n\n\n\nBio: Bo Peng is a computational scientist at Pacific Northwest National Laboratory (PNNL) in the Physical and Computational Sciences Directorate. His research operates at the intersection of many-body electronic structure theory\, Green’s-function approaches to spectroscopy and excited states\, quantum algorithms for chemistry and materials\, and advanced computing/HPC for large-scale simulation. He develops both theoretical frameworks and production-quality computational tools\, with contributions ranging from coupled-cluster/downfolding ideas to open quantum dynamics models that incorporate environmental memory. More broadly\, his work aims to connect accurate microscopic theory with scalable computation and emerging quantum hardware\, enabling predictive simulations of complex molecular and condensed-phase systems. He is also dedicated to mentoring and collaborates widely across national laboratories and academia.

SUMMARY:T Serkan Kasirga (Bilkent University): Optoelectronics and phase transitions of atomically thin materials via proximity engineering nbsp
DESCRIPTION:Speaker: T Serkan Kasirga\, Bilkent University\nUnlike three-dimensional materials\, screening of the interaction across quasiparticles in atomically thin materials can significantly alter their electronic and phononic properties. Earlier studies have demonstrated that dielectric screening can modify material parameters\, including electronic mobility\, conductivity\, Raman modes\, Seebeck coefficient\, and photoluminescence\, in semiconducting two-dimensional (2D) materials. In this talk\, I will discuss our efforts on finding novel two-dimensional materials with phase transitions via interlayer space modification and how screening modification via substrate engineering can be used in conjunction with scanning photocurrent microscopy to investigate the fundamental properties of 2D materials\, such as photoresponse mechanisms. Moreover\, I will illustrate how metals can be used to achieve screening\, despite the odds\, at the ultimate proximity to control the excitonic light emission from semiconducting 2D materials. Ultimately\, I will attempt to demonstrate how screening effects can be leveraged to enhance various electronic and optical properties of two-dimensional materials.

I will discuss applications of those techniques to modeling chemistry under electronic strong coupling\, and in using cavity-molecule interactions to generate entanglement. I will also highlight some pedagogical developments that we have developed to introduce students to computational molecular science tools within the context of strong light-matter coupling. \nAssociate Professor Jay Foley – Department of Chemistry\, University of North Carolina CharlotteHost: Niri Govind

However\, their development is hampered by a lack of rational design principles due to missing fundamental knowledge about how ion-charge interactions and dynamic polymer nanostructure influence charge transport and storage along polymer chains. In this talk\, I will first discuss how we are exploiting the ultrafast dynamics of photoexcited charge carriers to provide details on their nanoscale environment and trapping behavior. Then I will show how in situ electronic and vibrational spectroscopy of polymer electrodes can be used to track their complex nanoscale dynamics during charging\, revealing insights into nanostructures that support the formation of mobile carriers. \n  \nDr. Chris Grieco is an assistant professor of chemistry at Auburn University\, where his research group develops laser spectroscopy methods to probe charge carriers in conducting polymers used in electrochemical applications ranging from bioelectronics to batteries. Prior to Auburn\, Chris earned his Ph.D. in chemistry at Penn State University where he worked with Prof. John Asbury studying how to improve exciton and charge carrier dynamics in organic molecules and polymers for solar cells. Chris then worked with Prof. Bern Kohler as a postdoctoral scholar at the Ohio State University\, where he developed ultrafast transient absorption spectroscopy methods for probing the elusive structure and photochemistry of the eumelanin biopigment.

SUMMARY:IQuS Research Seminar: Stephen Jordan (Google Quantum AI)
DESCRIPTION:Optimization by Decoded Quantum Interferometry \n\n\n\nAchieving superpolynomial speedups for optimization has long been a central goal for quantum algorithms. I will discuss Decoded Quantum Interferometry (DQI)\, a quantum algorithm descended from Regev’s reduction\, that uses the quantum Fourier transform to reduce optimization problems to decoding problems. For approximating optimal polynomial fits over finite fields\, DQI achieves a superpolynomial speedup over known classical algorithms. The speedup arises because the problem’s algebraic structure is reflected in the decoding problem\, which can be solved efficiently. Whether DQI can also attain quantum advantage for algebraically unstructured optimization problems such as max-k-XORSAT remains an open question. One reason for optimism is that the sparsity of the clause structure in max-k-XORSAT is reflected in the dual decoding problem\, which is for LDPC codes. I will describe some current lines of attack on this open question\, as well as generalizations of DQI for preparing Gibbs states of Hamiltonians. This talk will target a broad audience without assuming deep background in quantum algorithms.

DESCRIPTION:Event interval: Single day eventCampus location: Bagley Hall (BAG)Campus room: 154Accessibility Contact: Matthew Yankowitz\, myank@uw.eduEvent Types: Lectures/Seminars \nTitle: Engineering Topological Quantum Matter in Space and Time. \nAbstract: Topology has emerged as a unifying principle in modern condensed matter physics and materials science\, enabling quantum phases that are remarkably robust yet exquisitely sensitive to their underlying environment. While traditional approaches to topological materials discovery rely on chemistry\, the rise of moiré quantum materials suggests a different strategy: engineering topology by tailoring the physical environment. \n In this talk I will highlight my group’s recent efforts to control scalable topological quantum matter using two fundamental physical knobs – space and time. We constructed a unique testbed to manipulate and probe materials at femtosecond time scale and atomic-layer spatial scale . In space\, by precision control of dimensionality\, we demonstrate 2-quintuple-layer Bi2Te3 and MnBi2Te4/Bi2Te3 as robust 2D topological insulators with an inverted gap greater than 100 meV\, suggesting a potential quantum spin Hall effect operating at ambient temperature . In time\, we show that topological electronic states carry intrinsic layer-dependent vibrational fingerprints. By “listening” to these frequencies as the states couple to coherent phonons\, we develop a quantum stethoscope capable of resolving long-standing puzzles in magnetic topological insulators\, including the elusive broken-symmetry energy gap . In combined space-time co-engineering\, I will present our latest results integrating photonic crystal cavities with ultrathin topological insulators to realize cavity-driven Floquet engineering . This platform represents a new class of physical-environment control experiments\, where the ground states of topological materials are reshaped simultaneously in space and time. Together\, these examples illustrate a paradigm in which topological phenomena can be designed and manipulated by engineering the physical environment\, and potentially stabilized near ambient conditions – opening pathways toward scalable quantum materials and devices. \nReferences C.

SUMMARY:Maxwell Parsons (University of Washington)\, QISE Seminar: Engineering Qubit Control for Scalable Quantum Systems
DESCRIPTION:Abstract \n\n\n\nQuantum computing is advancing along two primary scaling paradigms: distributed quantum systems connected through entanglement networks\, and increasingly large individual quantum processors. Both approaches require not only long-lived qubits\, but control architectures deliberately engineered to support error correction at scale. In my laboratory\, we investigate these paradigms through complementary experimental platforms: color-center quantum memories for networked architectures and reconfigurable neutral-atom arrays for large-scale processors. \n\n\n\nIn color-center systems\, an optically-addressable central electronic spin coherently couples to nearby nuclear spins to form a modular quantum memory with a photonic interface\, suitable for quantum networking. Here\, dominant limitations arise from structured environmental spin-noise and the common fluctuator associated with optical transitions of the electronic state. We are developing control strategies tailored to this noise environment\, engineering microwave and optical protocols that stabilize multi-spin registers and extend usable memory lifetimes in a manner compatible with networked error-correction schemes. \n\n\n\nIn neutral-atom systems\, we explore opportunities enabled by three-dimensional qubit geometries uniquely accessible in optically trapped atom arrays. Three-dimensional connectivity offers architectural advantages for efficient error correction\, but imposes stringent requirements on local optical control and crosstalk suppression. At the same time\, three-dimensional geometries can enable scaling in physical qubit number due to the re-use of optical power across layers of qubits for trapping and gate control.  We are co-designing 3D neutral-atom architectures and scalable optical control hardware to match qubit geometry to fault-tolerant operation and are establishing a dedicated testbed for developing and characterizing these strategies. \n\n\n\nAcross both efforts\, the central theme is control–architecture co-design: engineering qubit control systems that are intentionally matched to geometry\, noise environment\, and error-correction strategy. \n\n\n\nBio \n\n\n\nMax Parsons is an Assistant Professor in the Department of Electrical & Computer Engineering. His research focuses on advancing quantum hardware for computing\, sensing\, and communication by developing scalable control of neutral atoms and solid-state quantum systems. At UW\, he leads efforts in optical control of qubits and experimental testbeds for neutral atom quantum processors and spin-defect quantum memories.  Parsons completed his PhD in Physics at Harvard University in 2016\, where he pioneered techniques for laser cooling and atom-resolved imaging of fermionic atoms for quantum simulation. Prior to joining UW in 2022 to develop the QT3 lab\, he worked in industry on mixed-reality displays at Meta’s Reality Labs and on neutral-atom quantum computing hardware at Atom Computing. He is an inventor on more than 35 patents in quantum computing and mixed-reality technologies.

DESCRIPTION:Event interval: Single day eventCampus location: Electrical and Computer Engineering Building (ECE)Campus room: ECE 037Accessibility Contact: events@ece.uw.eduEvent Types: Lectures/SeminarsLink: https://www.ece.uw.edu/colloquia/middas-memory-integration-and-data-dis-aggregation/ \nMIDDAS: Memory Integration and Data Dis-Aggregation \nAbstract \nSince the invention of the integrated circuit in 1958\, the integration of exponentially more devices onto a single chip has transformed    computing—yet memory remains largely separated from logic\, resulting in a “memory wall”. Recent advances in memory research have introduced a variety of new memory technologies. My research focus\, Memory Integration and Data Dis-Aggregation (MIDDAS)\, envisions a future where massive\, diverse memories are physically integrated yet functionally store disaggregated data. MIDDAS encompasses a continuous spectrum of memory characteristics. This is exemplified by BRIDGE (Blended Retention-Indexed Diverse Gain cEll)\, a gain cell memory platform developed in my PhD research. The 2-transistor (2T) gain cell memory offers high density and CMOS integration compatibility. By introducing oxide semiconductor (OS) transistors with ultra-low leakage current (< 1e-17 A/μm)\, BRIDGE expands the design space to support retention times spanning microseconds to seconds. BRIDGE is demonstrated on fabricated N40 CMOS+X monolithic 3D integration chip with Atomic-Layer-Deposited (ALD) Indium Tin Oxide (ITO) FET. Hybrid gain cell (OS-Si) demonstrates 3x density and lower energy compared to high-density (HD) SRAM\, scalable to N5 and beyond. Furthermore\, integrating gain cells with non-volatile memories (e.g.\, RRAM) unlocks synergistic system-level benefits from device-circuit-architecture co-design\, embodying the “1+1>2” philosophy where diverse memory technologies collaboratively enhance system functionality through integration. MIDDAS repositions memory as a scalable\, intelligent toolbox for AI-era computing\, capitalizing on the predictability of memory access\, bridging device innovation with software demands. \nBiography \nShuhan Liu is a PhD candidate at Stanford University\, advised by H.-S. Philip Wong. She earned B.S. degree from Peking University in 2020. She received 2024 IEEE EDS PhD Fellowship and 2024 IEEE IEDM Best Student Paper Award.

SUMMARY:Evan Reed (IonQ)\, QISE Seminar: Flipping Molecules: An Experimental Demonstration of Dipole-Phonon Quantum Logic
DESCRIPTION:Abstract  \n\n\n\nTrapped atomic ions are one of the leading candidates for large-scale quantum technologies\, and many decades of research have gone into developing the techniques to coherently control the quantum states of atomic ions to make them a viable platform for engineering quantum technologies. The applications range from computation to communication networks to sensing. Molecular ions\, however\, remain under-researched. While their wealth of internal states makes them interesting candidates for quantum technologies\, it also makes them difficult to control. Here\, we demonstrate that by using the electric potential of the ion trap we can coherently\, and without lasers\, induce a transition between two internal states of a single molecular ion (CaO+) by means of a Jaynes-Cummings-type interaction. Then\, we use a co-trapped atomic ion (Ca+) to herald and measure the interaction via quantum logic spectroscopy. This procedure\, named dipole-phonon quantum logic (DPQL)\, enables state preparation and measurement of quantum information encoded in a molecular ion. Here\, I present the first demonstration of DPQL. We have shown the interaction signals to have a lower bound on the statistical significance as high as 4.92σ and posterior probability greater than 99%.  \n\n\n\nBio \n\n\n\nEvan Reed is an Atomic Physicist on the Science Team at the quantum technology company IonQ. He grew up in Georgia in the foothills of southern Appalachia\, and he attended the Georgia Institute of Technology for his BS in physics. There\, he trained in ion trapping under the guidance of Prof. Ken Brown. As Evan graduated from GT\, the Brown Lab moved from GT to Duke University. Evan rejoined the Brown lab at Duke as a PhD student in the department of electrical and computer engineering where he performed research in the coherent control of trapped molecular ions. Evan defended his dissertation in May of 2024 after which he joined IonQ and moved to Seattle. At IonQ\, he now works on the team that builds the prototypes of the most advanced generation of quantum computers and performs technology development for future generation systems.

SUMMARY:UW ECE Research Colloquium Lecture Series: Yanjie Shao\, Massachusetts Institute of Technology
DESCRIPTION:Campus location: Electrical and Computer Engineering Building (ECE)Campus room: ECE 037Accessibility Contact: events@ece.uw.edu \nEvent Link \nUltra-Scaled Energy-Efficient Electronics \nAbstract  \nThe explosive growth of data-centric computing in the era of artificial intelligence has made energy efficiency a central challenge for modern microelectronics. Two fundamental limitations now dominate: (1) the “power wall”\, where stalled voltage scaling in advanced complementary metal–oxide–semiconductor (CMOS) technologies has largely limited further reductions in transistor switching energy\, and (2) the “memory wall”\, where data movement between computing and memory units increasingly dominates energy cost and restricts information throughput. In this talk\, I will present two complementary approaches\, leveraging new material systems and nanoscale processing to enable unprecedented device operating regimes and scalable 3D integration paradigms beyond conventional CMOS scaling. First\, I target a supply voltage ≤ 0.3 V by exploiting quantum-mechanical tunneling in a broken-band heterojunction semiconductor system (GaSb/InAs). I will show that a combination of sub-thermionic turn-on\, high drive current and ultimate device scalability can be achieved simultaneously in a vertical-nanowire tunneling transistor configuration. Second\, I will describe a low-thermal-budget (≤ 400 °C) electronic technology integration platform enabled by amorphous oxide semiconductors (AOS) and ferroelectric (FE) hafnium-zirconium oxide. By exploiting plasma-enhanced atomic-layer deposition\, enhancement-mode AOS transistors with record logic performance are realized\, and nanoscale FE memory transistors comprising a single domain are demonstrated. Together\, these results highlight how emerging materials can drivehigh-performance and multifunctional devices that unlock new pathways for future energy-efficient 3D electronics. \nBiography  \nYanjie Shao is currently a postdoctoral researcher at the Massachusetts Institute of Technology (MIT) in the Microsystems Technology Laboratories (MTL)\, working with Prof. Jesús del Alamo and Prof. Dimitri Antoniadis.

SUMMARY:MSE Seminar: Aaron Sharpe
DESCRIPTION:Event interval: Single day eventCampus location: Bagley Hall (BAG)Campus room: 154Accessibility Contact: Matthew Yankowitz\, myank@uw.eduEvent Types: Lectures/Seminars \nTitle: Quantum Electronic Phases in Twisted Trilayer Graphene \nAbstract: Stacking layers of van der Waals materials with an interlayer twist modulates interlayer hopping on the moiré length scale\, enabling control over electronic band structure. We can extend upon this paradigm by introducing a third twisted layer. The system now contains two interfering moiré patterns that modulate the effective local electronic properties on a longer supermoiré length scale. Here\, I will provide two vignettes about the supermoiré system of twisted trilayer graphene. Together\, these studies establish an organizing framework for the correlated phases in twisted trilayer graphene. They reveal a direct correspondence between superconductivity and thermodynamic signatures of electronic correlations. Additionally they suggest a sensitive interplay of the supermoiré modulation and lattice relaxation that dictates the resultant phenomenology. \nFirst\, we will focus on a narrow region of the ‘angle-angle’ space that determines this trilayer structure. Using a scanning single-electron transistor\, we map the impact of electron-electron interactions as a function of twist angle in the sample. We observe gapped correlated insulators and a ‘sawtooth’ in electronic compressibility. Subsequent transport measurements in the same region reveal robust superconductivity. Our measurements indicate that superconductivity is not directly tied to the correlated insulators. Rather\, its critical temperature correlates closely with the strength of the sawtooth in compressibility\, possibly suggesting a common origin or link between the two. \nSecond\, I will discuss how the electronic phases evolve across a broad range of twist angles whose twist angles lie along two continuous lines in the twist-angle parameter space. Different points along these lines exhibit differing phenomenology\, pointing to other variables beyond twist-angle. Theoretical calculations that lattice relaxation in twisted trilayer graphene depends sensitively on both the magnitude and the relative handedness of the angles. \nBio: Dr. Aaron Sharpe is an Associate Scientist at SLAC National Laboratories and Stanford University\, having received his Ph.D. in Applied Physics from Stanford University in 2020 and following a Truman Fellowship at Sandia National Laboratories from 2020 to 2023. Aaron has made a number of key contributions to the world of van der Waals systems\, including the discovery of orbital ferromagnetism in twisted bilayer graphene for which he was awarded UIUC's prestigious McMillan award. His work further includes some of the first evidence of strong correlations in rhombohedral graphene systems. At present\, Aaron focuses on exploring strong correlations in various trilayer moiré systems and rhombohedral graphene systems in the absence of a moiré potential.

SUMMARY:Daniel Higginbottom (Simon Fraser University)\, QISE Seminar: Engineering silicon colour centres for quantum networks
DESCRIPTION:Abstract \n\n\n\nThe performance of quantum networks for long-distance communication\, sensing\, and distributed quantum computing will be contingent upon the quality of their light-matter interconnects. For networks at scale\, these interconnects should be manufacturable and deployable. Solid-state colour centres are single-photon emitters which may offer optically-coupled spin qubit registers for deployable entanglement distribution networks. Of the potential semiconductor hosts\, silicon is an ideal platform for commercial quantum technologies. It is a “semiconductor vacuum” with record-setting spin qubit performance\, and silicon nanofabrication is an advanced industrial process and the backbone of the microelectronics industry. Although they were neglected until quite recently\, silicon colour centres are now established as a quantum platform with technological appeal: they emit in or near the optical telecommunications bands\, host intrinsic spin qubit registers\, and integrate directly with photonic and electronic circuits on chip. In this talk I will discuss progress towards networked silicon colour centre devices and identify emerging candidates from the rapidly expanding alphabet of silicon colour centres. In particular\, I will summarize recent results with the T centre\, a CCH defect in silicon. A surprising isotope-dependent lifetime effect suggests that the T centre can be made almost perfectly efficient by isotopic substitution. Cavity-integrated T centres show dramatic Purcell enhancements\, enabling faster and more coherent emission\, and indistinguishable emission is employed to entangle T centres on separate chips\, six meters apart. Determining the hyperfine tensors of the T centre’s intrinsic spin qubits reveals unusual schemes for protecting spin coherence during entanglement attempts. Finally\, a new class of opto-electronic devices combining single emitters\, optical resonators\, and diodes enable a host of spin-photon control techniques including electrically-injected single-photon emission\, Stark tuning\, and electrical spin initialization. These results illustrate how silicon colour centres may be deployed as an on-chip spin-photon quantum processor\, and how these processors may be connected over optical fibre in a metropolitan-scale quantum internet.Bio  \n\n\n\nDr Daniel Higginbottom is an Assistant Professor in the Simon Fraser University Department of Physics and a Director at the quantum technology company Photonic Inc. His research has spanned quantum information with platforms including integrated photonics\, optically trapped atoms\, electrically trapped ions\, and silicon spin qubits\, for which he received a Banting Research Fellowship. His achievements include benchmark results with single photon sources and optical quantum memories. Recently\, he has pioneered the device integration of silicon colour centres\, most notably the T centre\, for quantum technologies. The primary goal of his research is developing practical\, and scalable\, quantum technology platforms.

SUMMARY:Kirk Madison (University of British Columbia): Tuning the sharpness of quantum measurements using position entangled atomic states
DESCRIPTION:Speaker: Kirk Madison\, University of British ColumbiaAs rigorously proven by Paul Busch in 2007\, quantum systems are necessarily disturbed by measurement .  The amount of disturbance\, interpreted here as state change\, is related to the information gained\, hence a measurement scheme that induces no state change yields no new information. Standard projective measurements\, such as the measurement of an excited state energy (with respect to the groundstate) by coupling a quantum system to a photon and then detecting the photon absorption\, are maximally disruptive since they project the initial state of the system into an eigenstate of the measured observable.  By contrast\, so-called weak measurements provide an observer with little information and\, in turn\, disrupt the quantum state very little.  Also\, known as ‘unsharp’\, ‘fuzzy’ or ‘gentle’\, such measurements have been considered in the context of measuring the quantum trajectory of a system using weak continuous measurements . One scheme for implementing unsharp measurements is to first entangle a target quantum system with an ancillary quantum system and then carry out a measurement on the ancilla.  By adjusting the degree of entanglement\, the sharpness of the measurement on the target system can be controlled. In this talk\, we explore how tunable position-entangled quantum states of atoms can be used to realize tunable quantum measurements.  Entangled states of atomic pairs are created by Feshbach resonance coupling and measurements of the ancilla are conducted either by ancilla selective scattering of single photons or by hard collisional localization of the ancilla by the scattering of room-temperature atoms in the background vapor of the apparatus.

SUMMARY:Michael Beverland (IBM)\, QISE Seminar: Real-time decoding for fault-tolerant quantum computers
DESCRIPTION:Abstract: Fault-tolerant quantum computers involve running circuits on quantum hardware that sometimes undergo faults in such a way that the faults can be identified and fixed to ensure the quantum computation runs reliably. To do this\, information is protected in a quantum error correcting code\, and carefully-designed logical operations are carried out on the protected information\, with information about the noise that arises during the entire process being generated in a continuous stream of classical output called the syndrome. Decoding is the task of taking the syndrome data and using it to identify what faults occurred so that they can be fixed. This decoding task is run on a classical computer\, and is needed to make the quantum computer work – but it is a very challenging unsolved problem to design a decoding algorithm that performs well enough in practice.Real-time decoding for fault tolerance is a central challenge as we move beyond NISQ. The decoding timescale is set by the QEC cycle time of the hardware\, which is microseconds for superconducting platforms. Meeting this constraint likely requires specialized classical hardware such as FPGAs or ASICs\, whose high degree of parallelism changes the relative performance of decoding algorithms\, for example allowing Gaussian elimination to run in linear parallel time on FPGAs rather than cubic time on CPUs\, and therefore motivates hardware-aware redesign rather than direct porting of CPU-based methods.In this talk\, I discuss recent progress toward real-time decoding under these constraints\, and argue that message-passing decoders\, particularly the Relay-BP algorithm\, offer a promising route to real-time decoding. Relay-BP improves on the convergence of standard belief propagation while retaining a lightweight\, highly parallel structure suitable for FPGA implementation\, and significantly outperforms alternative decoders for quantum LDPC codes.Beyond average decoding speed\, I address the backlog problem that arises from variable decoding latency. I present conditions on decoder latency distributions under which fast average-case decoding and sufficiently light latency tails allow decoding to keep pace with syndrome generation\, ensuring bounded computational slowdown in large-scale fault-tolerant computations. \n\n\n\n \n\n\n\nLinkedIn: Michael Beverland

They exhibit extraordinary selectivity\, scalability\, and tunability\, and offer a promising new toolbox for solar to chemical energy conversion and chemical synthesis. However\, the understanding and design of photoenzymes pose several challenges. First\, accurate first-principles simulations of the electronic structure of macromolecules are usually computationally expensive\, especially those that involve strong electron correlation. In this talk\, I will discuss our computational strategies\, including data-driven methods and quantum computing to tackle this challenge. Second\, existing enzyme design strategies do not consider electronic excited states\, and photoenzyme engineering has mainly relied on directed evolution. I will discuss our work on physics-informed computational photoenzyme design\, where we combine physics-based simulations and data-driven methods to demonstrate that microenvironment tuning is a promising design strategy for photoenzymes and other macromolecular photocatalysts.                       Dr. Sijia Dong is an assistant professor in the Department of Chemistry and Chemical Biology at Northeastern University\, with affiliations in the Department of Physics and the Department of Chemical Engineering. She received her PhD in Chemistry from California Institute of Technology in 2017\, advised by Prof. William A. Goddard III. She carried out her postdoctoral research at the University of Minnesota with Prof. Donald G. Truhlar and Prof. Laura Gagliardi\, and then at Argonne National Laboratory with Prof. Giulia Galli. Research in the Dong Lab focuses on developing and applying physics-based and data-driven computational methods on both classical and quantum computers to accelerate chemical discoveries. Sijia has been selected a Scialog Fellow for Automating Chemical Laboratories by Research Corporation for Science Advancement\, has won the American Chemical Society COMP OpenEye Cadence Molecular Sciences Outstanding Junior Faculty Award\, the Inter-American Photochemical Society Young Investigator Award\, and the Northeastern University College of Science Excellence in Mentorship Award\, has a Maximizing Investigators’ Research Award for Early Stage Investigators from the National Institutes of Health\, and is recognized as an Emerging Investigator by the Journal of Chemical Physics\, American Institute of Physics. Sijia also co-chairs the Early Career Board of the Journal of Chemical Theory and Computation.
