摘      要：Photonic quantum technologies hold promise to repeat the success of integrated nanophotonic circuits in non-classical *** linear optical elements,quantum optical computations can be performed with integrated optical circuits and can therefore overcome the existing limitations in terms of *** addition to passive optical devices for realizing photonic quantum gates,active elements,such as single-photon sources and single-photon detectors,are essential ingredients for future optical quantum *** systems that allow for the monolithic integration of all components are particularly attractive,including III-V semiconductors,silicon and ***,we demonstrate nanophotonic integrated circuits made from high-quality polycrystalline diamond thin films in combination with on-chip single-photon *** using superconducting nanowires that are coupled evanescently to traveling waves,we achieve high detection efficiencies of up to 66%as well as low dark count rates and a timing resolution of 190 *** devices are fully scalable and hold promise for functional diamond photonic quantum devices.
