Generation of heralded entangled photon combs at telecom wavelength with rubidium Rydberg atom cavity QED
Sutapa Ghosh, Nick Rivera, G. Eisenstein, Ido E. Kaminer · 2020
We proposed a protocol to generate entangled photon-comb pairs using rubidium Rydberg atoms inside an optical cavity. Rydberg blockade isolates a single excitation and the heralding enables non-destructive detection of the presence of photon-pairs.
