Query: Hybrid photonic circuit for multiplexed heralded single photons   A key resource for quantum optics experiments is an on-demand source of
single and multiple photon states at telecommunication wavelengths. This letter
presents a heralded single photon source based on a hybrid technology approach,
combining high efficiency periodically poled lithium niobate waveguides,
low-loss laser inscribed circuits, and fast (>1 MHz) fibre coupled
electro-optic switches. Hybrid interfacing different platforms is a promising
route to exploiting the advantages of existing technology and has permitted the
demonstration of the multiplexing of four identical sources of single photons
to one output. Since this is an integrated technology, it provides scalability
and can immediately leverage any improvements in transmission, detection and
photon production efficiencies.
