Silicon Photonic Quantum Computing

PsiQuantum’s goal is to build the world’s first useful quantum computer using silicon photonic chips to process quantum information with single photons. A linear optical approach to quantum computing offers highly coherent qubits, high fidelity single qubit gates, and probabilistic entangling operations that can be implemented using well-known quantum optical methods. Architectures for fault tolerant quantum computing based on these operations can have very low optical depth and extremely high tolerance to optical loss. The key advantage of photonic quantum computing is the fact that the required photonic chips can be produced in conventional fabrication facilities used for commercial silicon photonics, allowing scaling to achieve large-scale error correction. We will discuss PsiQuantum’s approach to fault tolerant quantum computing.
