Jeremy O'Brien

Prof. Jeremy O’Brien is co-founder and CEO of PsiQuantum, a quantum computing company soon to deliver the world’s first commercially useful quantum computers. These systems will be used to tackle some of the greatest challenges we face, and to create profound new opportunities. PsiQuantum is partnering with customers and governments globally to bring about transformation across healthcare, climate, finance, transportation, security and beyond.

Prof. O’Brien has dedicated 25 years to this mission, having identified quantum computing as the most profoundly world-changing technology, due to its potential to unlock critical solutions to otherwise impossible problems. PsiQuantum has invented a ‘fusion-based’ photonic architecture to enable utility-scale quantum computers to be manufactured in a conventional silicon chip foundry, and leverage the full semiconductor, packaging and computer systems supply chain, and to achieve compatibility with conventional control electronics, optical fibre networking and existing large-scale cryogenic infrastructure.

Prof. O’Brien has published 150 papers with 40,000 citations (h-index 88); he demonstrated the first photonic 2-qubit logic gate, invented the field of Integrated Quantum Photonics, co-invented the Variational Quantum Eigen Solver (VQE), and implemented VQE on a photonic chip. Prior to founding PsiQuantum, he was Professor of Physics and Electrical Engineering at Stanford and Bristol Universities, and Founding Director of the Centre for Quantum Photonics/QET Labs. He has held visiting professorships at NTT, Osaka University, Hokkaido University and the University of Tokyo, totaling two years. He received a Ph.D. from the University of New South Wales and is an undergraduate and postdoc alumnus of the Universities of Western Australia and Queensland, respectively. He holds a Royal Academy of Engineering Research Chair in Emerging Technologies, and is a Fellow of the American Physical Society and the Institute of Physics.
