PsiQuantum

PsiQuantum is a Silicon Valley-based quantum computing company focused exclusively on building the world’s first utility-scale, fault-tolerant quantum computer using photonic technology and standard silicon chip manufacturing. Unlike other quantum hardware companies offering near-term cloud access, PsiQuantum is taking a long-term approach — leveraging existing semiconductor fabrication infrastructure at GlobalFoundries to manufacture photonic quantum chips at scale. PsiQuantum’s architecture is designed from the ground up for fault tolerance, targeting a million-qubit system capable of solving problems beyond the reach of any classical supercomputer. Ideal for enterprises and research institutions planning for the fault-tolerant quantum computing era.
