PsiQuantum is building a quantum computer on single particles of light. The chips are printed at a commercial semiconductor fab, and the goal is a million-qubit machine. Founded in 2016 in Palo Alto. The first two industrial sites are already under construction, in Queensland and Chicago: work began at Moreton Bay on the site of a former paper mill on June 17, 2026. In July 2026 Victor Peng, former president of AMD and head of Xilinx, became CEO, while founder Jeremy O'Brien moved to executive chairman; in April, Intel CEO Lip-Bu Tan joined the board. Current valuation is $7B from a Series E (September 2025); $1.67B raised across five rounds since 2016.
