Laser allows solid-state refrigeration of a semiconductor material

Posted Posted in News

A team led by materials science and engineering professor Peter Pauzauskie used an infrared laser to cool a solid semiconductor by at least 20 degrees C, or 36 F, below room temperature. Their findings were reported in a paper published June 23 in Nature Communications. Lasers that can cool materials could be adapted in the future by scientists from various fields to enhance the performance of quantum sensors.

Quantum computing is the key to solving problems regular computers can’t handle, like designing silver-bullet drugs for cancer or improving materials for data storage. QuantumX is bringing together quantum expertise across the UW campus to stimulate research and teaching on all things quantum.

New method to dope nanodiamonds for quantum computing

Posted Posted in News

A team led by UW Professor Peter Pauzauskie discovered that they can use extremely high pressure and temperature to introduce other elements into nanodiamonds, making them potentially useful in quantum communications and quantum sensing. This work was done in collaboration with the U.S. Naval Research Laboratory and the Pacific Northwest National Laboratory and published in Science Advances.
