Biography:
Ray Beausoleil is a Principal Scientist at HP Laboratories currently conducting basic research in nanoscale classical and quantum optics for information processing applications. Ray’s work is focused on basic experimental research on the fundamental physical processes that govern optical quantum information technologies (QIT), and — in collaboration with scientists and engineers in the Quantum Information Processing department in Advanced Studies and the Systems Research Lab — the search for few-qubit applications of those technologies that could allow HP to gain a commercial foothold in QIT within the next ten years. During his career, Ray has concentrated on advanced industrial applications of physics, mathematics, and numerical and computer algorithms to research on fundamental problems in laser physics, nonlinear optics, and quantum optics. Ray is the principal investigator for several federally-funded programs, including “Applications of Slow Light to Information Processing” and “Bootstrapping a Quantum Information Technology” with DARPA.

As a Visiting Scientist in the Applied Physics Department of Stanford University, Ray is responsible for leading the research, development, and implementation of a numerical model of the optical response of the NSF Laser Interferometer Gravitational-Wave Observatory (LIGO) detector to environmental perturbations, thermal focusing and deformations, and gravitational radiation. He is also an active member of the LIGO Scientific Collaboration, which oversees gravitational wave research and development programs conducted by the National Science Foundation.

Education:
Ph.D. in Physics, Stanford University, 1987.
