What PsiQuantum does
PsiQuantum is a private company founded in 2016 and headquartered in Palo Alto, California, that is building and deploying utility-scale, fault-tolerant quantum computers using a silicon photonics approach. Its core technology is the Omega chipset — a purpose-built silicon photonic chipset manufactured at GlobalFoundries' flagship 300mm semiconductor fab in Malta, New York — which enables the company to leverage mainstream semiconductor manufacturing and industrial cryogenics (4 Kelvin operation) rather than the exotic millikelvin cooling required by superconducting and trapped-ion modalities. The architecture encodes qubits into single photons and uses standard telecom optical fiber to scale across chips and facilities without transduction, with the company targeting systems on the order of one million physical qubits. Key proprietary components include the fusion-based fault-tolerant architecture, Active Volume Compilation (which delivers approximately 50x run-time efficiency gains and reduces a 2048-bit RSA factoring estimate to ~9 hours), and the Construct FTQC software platform integrated with NVIDIA CUDA-Q for GPU-accelerated simulation.
The company is pre-commercial for its flagship hardware product. Current revenue derives from a portfolio of non-dilutive and dilutive government contracts (DARPA US2QC and Quantum Benchmarking Initiative, AFRL $10.8M, US CHIPS Act $100M Letter of Intent for minority equity, Australian Commonwealth and Queensland A$940M / US$620M, UK Government £9M, Japan NEDO) and bespoke R&D collaboration agreements with marquee enterprise partners across aerospace and defense (Airbus, Lockheed Martin), chemicals and advanced materials (Mitsubishi Chemical, MUFG), healthcare (National Cancer Center Japan), and automotive (Mercedes-Benz). PsiQuantum also operates the Qlimate climate-technology initiative with MUFG, the free open-access Construct software stack (with paid Early Access Program tiers), and open-source developer tools (QREF, Bartiq, Circuit Designer) intended to seed ecosystem adoption ahead of hardware availability.
The company's go-to-market is a high-touch, sovereign-and-enterprise field-sales motion backed by a dedicated Government Advisory Board, an EVP for U.S. Public Sector, and direct utility-scale site partnerships with the U.S. (Chicago IQMP, former U.S. Steel South Works, 300,000+ square feet), Australia (Moreton Bay Central, Queensland), and the UK (Sci-Tech Daresbury R&D facility). Manufacturing is fulfilled through GlobalFoundries for chip fabrication and Linde Engineering for one of the largest cryoplants ever built for quantum computing. Leadership was strengthened in 2026 with the appointment of Victor Peng (former AMD President, ex-Xilinx CEO) as Interim CEO and the addition of Intel CEO Lip-Bu Tan to the Board of Directors, signaling a transition from R&D to large-scale industrial deployment.
