We experimentally demonstrate a technique for shaping the temporal quantum waveform of
narrow-band biphotons generated in a cold atomic ensemble via four-wave mixing by …

We present our recently-built experimental setup designed to generate near-infrared and
narrow-band correlated photon pairs by inducing four-wave mixing in a cold gas of 87Rb …

Photon-pair sources from atomic ensembles are considered essential to the development of
quantum science and technology based on atom-photon interfaces. The measurement of …

The nonclassical photon pair, generated via a parametric process, is naturally endowed with
a specific form of frequency-time quantum correlations. Here, we report complete control of …

Non-classical paired photons are generated by a four-wave mixing process in a far-detuning
three-level system with cold atoms. A violation of the Cauchy-Schwartz inequality of a factor …

We have theoretically studied the space-time entangled biphoton state generated from a two-
level atomic system. In the photon counting measurement, the two-photon coincidence …
