PsiQuantum’s mission is to build and deploy useful, fault tolerant quantum computers

After more than a decade of academic research, PsiQuantum was founded on the premise that photonic qubits, together with leverage of mature semiconductor manufacturing processes, could provide a fast path to a commercially useful, million-qubit quantum computer.

Now, PsiQuantum builds thousands of wafers of quantum chips in a tier-1 foundry, operates cryogenic cabinets designed to support hundreds of chips, and is optimizing fault-tolerant algorithms that will solve valuable problems using our first-generation computers.

Large-scale quantum computers will prove enormously consequential for governments worldwide. PsiQuantum is working closely with governments to explore how fault tolerant quantum computing can help address pressing challenges facing vital industries, as well as national security. The company’s Government Advisory Board—with combined decades of public service, policy experience, and research expertise—serves as a vital channel for engagement with public-sector partners, and its members provide crucial independent perspective and strategic insight.
