Quantum computing with silicon photonics

PsiQuantum's goal is to build the world's first useful quantum computer using an integrated silicon photonics platform. Photonic qubits are highly coherent, have high fidelity single-qubit operations, can be entangled probabilistically by fusion measurements, and connected over long distances by standard optical fiber. The circuits that create, manipulate, entangle, and measure them can be manufactured in a commercial semiconductor foundry. With this platform we leverage the manufacturing scale, precision, and quality control that has been developed by the industry over decades of research and development. We will discuss PsiQuantum's unique approach to developing hardware that enables fault-tolerant quantum computing.
