摘要

Although holding great promise for low noise, ease of operation and networking1, useful photonic quantum computing has been precluded by the need for beyond-state-of-the-art components, manufactured by the millions2, 3, 4, 5-6. Here we introduce a manufacturable platform7 for quantum computing with photons. We benchmark a set of monolithically integrated silicon-photonics-based modules to generate, manipulate, network and detect heralded photonic qubits, demonstrating dual-rail photonic qubits with 99.98% +/- 0.01% state preparation and measurement fidelity, Hong-Ou-Mandel (HOM) quantum interference between independent photon sources with 99.50% +/- 0.25% visibility, two-qubit fusion with 99.22% +/- 0.12% fidelity and a chip-to-chip qubit interconnect with 99.72% +/- 0.04% fidelity, conditional on photon detection and not accounting for loss. We preview a selection of next-generation technologies: low-loss silicon nitride (SiN) waveguides and components to address loss, as well as fabrication-tolerant photon sources, high-efficiency photon-number-resolving detectors (PNRDs), low-loss chip-to-fibre coupling and barium titanate (BTO) electro-optic phase shifters for high-performance fast switching.
