Advances in Silicon Quantum Photonics

摘要: Quantum technology is poised to enable a step change in human capability for computing, communications and sensing. Photons are indispensable as carriers of quantum information—they travel at the fastest possible speed readily protected from decoherence. However, system requires thousands near-transparent components with ultra-low-latency control. To be implemented, new paradigm photonic required: one in-built coherence, stability, ability define arbitrary circuits, path manufacturability. Silicon photonics has unparalleled density component performance, which, CMOS compatible fabrication, place it strong position scalable platform. This paper progress report on silicon photonics, focused developments past five years. We provide an introduction challenges field, summarise current state-of-the-art identify outstanding technical challenges, well promising avenues future research. also resolve conflict definition Hong-Ou-Mandel interference visibility integrated experiments, needed fair comparison photon quality across different platforms. Our aim development scalability platform, which end we point way ever-closer integration, toward systems-on-a-chip.
