摘 要：Quantum-photonic chips,which integrate quantum light sources alongside active and passive optical elements,as well as singlephoton detectors,show great potential for photonic quantum information processing and quantum *** semiconductor nanofabrication processes allow for scaling such photonic integrated circuits to on-chip networks of increasing ***-order nonlinear materials are the method of choice for generating photonic quantum states in the overwhelming majority of linear optic experiments using bulk components,but integration with waveguide circuitry on a nanophotonic chip proved to be ***,we demonstrate such an on-chip parametric down-conversion source of photon pairs based on second-order nonlinearity in an aluminum-nitride microring *** show the potential of our source for quantum information processing by measuring the high visibility anti-bunching of heralded single photons with nearly ideal state *** down-conversion source yields measured coincidence rates of 80 Hz,which implies MHz generation rates of correlated photon *** noise performance is demonstrated by measuring high coincidence-to-accidental *** generated photon pairs are spectrally far separated from the pump field,providing great potential for realizing sufficient on-chip filtering and monolithic integration of quantum light sources,waveguide circuits and single-photon detectors.
