Allen School of Computer Science & Engineering\nwww.cs.washington.eduLink: https://www.cs.washington.edu/events/colloquia/details?id=3381AbstractAbstract is forthcoming.BioMike Dodds joined Galois in 2017 as a Principal Scientist. He specializes in applying formal methods to systems engineering problems in areas such as cryptography\, distributed protocols\, cyber-physical systems\, and hardware semantics. Much of Mike’s work has focused on building tools that can be used by non-expert developers as part of their regular engineering workflow.Mike has led a range of projects at Galois\, including our work on CN\, a unified testing and verification tool for C code; Daedalus\, a safe parsing language developed under the DARPA SafeDocs project; c2rust\, a transpiler used by several popular Rust crates; and several verified cryptography projects using SAW and Cryptol\, including a long-running collaboration with Amazon Web Services on core components of their AWS-LibCrypto library.Mike received his PhD from the University of York\, UK\, in 2008\, under the supervision of Dr. Detlef Plump. He then spent four years as a postdoctoral researcher at the University of Cambridge\, working with Dr. Matthew Parkinson and Prof. Peter Sewell. He returned to the University of York as a lecturer (in US terms\, an associate professor) from 2012 to 2017\, before joining Galois.This lecture will be streamed live and recorded.

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:William Kretschmer (University of Texas at Austin)\, QISE Seminar: Demonstrating an unconditional separation between quantum and classical information resources
DESCRIPTION:Abstract: \n\n\n\nA longstanding question in the foundations of quantum mechanics is whether the exponential state space of a quantum system is a physically accessible resource\, or whether the observed behavior of quantum devices admits a succinct classical explanation. In this talk I will discuss an experimental work in which\, leveraging quantum-classical separations in communication complexity\, we performed a task using 12 trapped-ion qubits that would provably require at least 62 bits of storage to replicate using classical information resources. Consequently\, no classical ontological model of fewer than 62 bits can explain the observed behavior of the 12-qubit system. Our separation does not rely on any unproven conjectures\, and demonstrates how today’s quantum processors can generate and manipulate entangled states of sufficient complexity to access the exponentiality of Hilbert space. Based on arXiv:2509.07255. \n\n\n\nSpeaker Bio: \n\n\n\nWilliam Kretschmer is an Assistant Professor in the Department of Computer Science at UT Austin. Previously\, was a Quantum Postdoctoral Fellow at the Simons Institute for the Theory of Computing. His research lies broadly in quantum information and computation\, with connections to complexity theory\, cryptography\, and learning. Kretschmer is especially interested in understanding computational problems that involve operation on quantum inputs.

SUMMARY:Separating QMA and QCMA with a classical oracle\, Chinmay Nirkhe
DESCRIPTION:Abstract:  \n\n\n\nWe construct a classical oracle proving that\, in a relativized setting\, the set of languages decidable by an efficient quantum verifier with a quantum witness (QMA) is strictly bigger than those decidable with access only to a classical witness (QCMA). The separating classical oracle we construct is for a decision problem we coin spectral Forrelation — the oracle describes two subsets of the boolean hypercube\, and the computational task is to decide if there exists a quantum state whose standard basis measurement distribution is well supported on one subset while its Fourier basis measurement distribution is well supported on the other subset. This is equivalent to estimating the spectral norm of a “Forrelation” matrix between two sets that are accessible through membership queries. \n\n\n\nOur lower bound derives from a simple observation that a query algorithm with a classical witness can be run multiple times to generate many samples from a distribution\, while a quantum witness is a “use once” object. This observation allows us to reduce proving a QCMA lower bound to proving a sampling hardness result\, which does not simultaneously prove a QMA lower bound. To prove said sampling hardness result for QCMA\, we observe that quantum access to the oracle can be compressed by expressing the problem in terms of bosons — a novel “second quantization” perspective on compressed oracle techniques\, which may be of independent interest. Using this compressed perspective on the sampling problem\, we prove the sampling hardness result\, completing the proof. \n\n\n\nJoint work with John Bostanci\, Jonas Haferkamp\, and Mark Zhandry: https://arxiv.org/abs/2511.09551
