PsiQuantum is a company that is building a general-purpose silicon photonic quantum computer. The company was founded in 2016 by Jeremy O'Brien, previously a Professor of Physics and Electrical Engineering at Stanford University and director of the Centre for Quantum Photonics at Bristol University. In 2019, PsiQuantum raised $230M in funding, investors include a venture capital fund co-founded by former Google executive Andy Rubin. The company is based in Slough, Berkshire and Palo Alto, California.
Based on technology developed at the University of Bristol PsiQuantum is using a silicon-based photonic approach to manufacturing a quantum computer in a CMOS silicon fab. PsiQuantum aims to offer numerous advantages compared to other quantum computing technologies, such as low noise, low-temperature operation, and no atomic-scale fabrication.
Founded by British scientists from Cambridge, Jeremy O’Brien, a physicist at the University of Bristol and Terry Rudolph, a professor at Imperial College London, PsiQ is attempting to bring quantum computing to regular desktop computers using a technique to encode information in photons as opposed to electrons. The technology as yet is unproven.
Funded by Android founder, Andy Rubin's Playground Ventures.
The company has relocated from Cambridge, UK to Palo Alto California to access funding and scale up. It hired Stu Aaron, previously a partner at Khosla Ventures as COO.
