The non-deterministic nature of photon sources is a key limitation for single-photon quantum processors. Spatial multiplexing overcomes this by enhancing the heralded single-photon yield without ...

The blue and red rays represent different subchannels over the frequency domain. The subchannel switching is operated at the cost of a temporal guard frame determined by the switching time of ...

Researchers have developed a microscopic 3D-printed optical device that can efficiently combine light from dozens of small semiconductor lasers into a single multimode optical fiber with very low loss ...
