PsiQuantum

PsiQuantum is working on developing a quantum computer that leverages silicon photonics technology. Unlike the matter-based approach to quantum computing, PsiQuantum asserts they gain advantages from more than 50 years of research and trillions of dollars invested in silicon wafer technology. Their goal is to utilize photonic qubits in their computing solutions, thereby avoiding the need to create new quantum technologies to generate qubits from solid matter, as their competitors must do.

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.
