The nonclassical photon pair is naturally endowed with a specific form of frequency-time quantum correlations. Here, we report complete control of time quantum correlations of narrowband biphotons generated in a cold atomic ensemble.
A specific form of frequency-time quantum correlations is naturally inherent in the nonclassical photon pairs generated via a parametric process. Here, complete manipulation of frequency-time quantum correlations of narrowband biphotons is reported.
