Spontaneous two-photon emission (STPE) refers to a pure quantum mechanical process in which vacuum fluctuations drive the emission consisting of a pair of highly correlated single photons. From the ...

Figure | Operation principle of the monolithic microcavity-metalens interfaces. (a) Schematics of the monolithic microcavity-metalens interface. A QD-micropillar single-photon device emits bright and ...

Photon loss is the biggest problem for scalable photonic quantum information processing. This issue can be tackled through quantum error correction, provided that the ...
