Jeremy O'Brien is cofounder and CEO of PsiQuantum. PsiQuantum is building a large-scale general-purpose silicon photonic quantum computer to solve the many important problems that will forever be beyond the capabilities of any conventional computer. Prior to founding the company, Jeremy was Professor of Physics and Electrical Engineering at Stanford and Bristol Universities and Director of the Centre for Quantum Photonics. He has spent more than 20 years working towards scalable quantum computing, including: micro-, nano-, and atomic-scale design; fabrication and operation of superconducting and semiconductor devices; design, construction, and operation of cryogenic and ultra-high vacuum systems; design, construction, and application of low-noise electrical measurement to organic-, super-, and semi-conductor (nano)structures; and the theory of quantum computing.
