A wide range of quantum communication, sensing and computation schemes can be implemented with single-photons. Here we envision a versatile photonic quantum information processing system on a silicon chip, which relies on nanophotonic circuits that integrate non-classical light sources and single-photon detectors in a scalable way. Single-photons are generated on-chip via spontaneous parametric down conversion or emission from nitrogen vacancy centers or single molecules. We design efficient interfaces between these sources and optical waveguides that feed into on-chip photonic networks. We realize building blocks of these networks that combine optical, electrical and mechanical functionality by leveraging modern nanofabrication technology and by exploring novel material systems as well as non-traditional design approaches. Waveguide-coupled superconducting nanowire single-photon detectors integrate seamlessly with such photonic circuitry and offer high detection efficiency, low noise and excellent timing performance. We investigate novel superconducting material systems that are favorable for high-yield production and operation at elevated temperatures. We present first steps towards integrating sources, circuits and detectors on-chip to match the demands of future large-scale implementations of quantum technologies.
