About

Peter McMahon is a physicist and engineer who uses tools from quantum and nonlinear optics, condensed-matter physics, and computer science to explore physical computation.

He and his lab research how to harness the computational capabilities of physical systems, with the ultimate goal of learning how to build computers that perform at the limit of what physics allows.

Much of his lab’s work concerns the development and application of quantum computers. His lab has an emphasis on photonic and superconducting-circuit approaches to building quantum-information-processing hardware. The lab’s work on applications is heavily focused on exploring what near-term, noisy quantum computers are capable of doing, especially in the areas of quantum simulation, optimization, and machine learning.
