PsiQuantum Corporation

Private Equity backed and Privately Held. PsiQuantum has one mission: To build and deploy the first useful quantum computers. In 2015, PsiQuantum was founded after the founders realized they had identified a viable path to build large-scale, fault-tolerant systems by taking a photonics approach and leveraging the advanced semiconductor manufacturing industry and existing infrastructure. Nearly nine years later, PsiQuantum is building thousands of wafers of quantum chips, testing production cryogenic cabinets and developing fault-tolerant algorithms to deploy on our first systems. https://www.psiquantum.com/about
