Active temporal multiplexing of indistinguishable heralded single photons
Active temporal multiplexing of indistinguishable heralded single photons
It is a fundamental challenge in quantum optics to deterministically generate indistinguishable single photons through non-deterministic nonlinear optical processes, due to the intrinsic coupling of single- and multi-photon generation probabilities in these processes. Actively multiplexing photons generated in many temporal modes can decouple these probabilities, but key issues are to …
