Is a rubidium cell with long decay time always useful for generating a non-classical photon pair?
Qun-Feng Chen, Xiao-Song Lu, Bao-Sen Shi +1
We experimentally find an interesting and unexpected thing: a rubidium cell with long decay time can not be used to generate a non-classical correlated photon pair via the D2 trans…
Control of light speed: From slow light to superluminal light
Qun-Feng Chen, Yong-Sheng Zhang, Bao-Sen Shi +1
A scheme for controlling light speed from slower-than-c to faster-than-c in an atomic system is presented in this paper. The scheme is based on far detuning Raman effect. Two far d…
Entanglement of the orbital angular momentum states of the photons generated in a hot atomic ensemble
Qun-Feng Chen, Bao-Sen Shi, Yong-Sheng Zhang +1
Quantum protocols will be more efficient with high-dimensional entangled states. Photons carrying orbital angular momenta can be used to create a high-dimensional entangled state.…
Observation of time correlation function of multimode two-photon pairs on a rubidium D line
Fu-Yuan Wang, Bao-Sen Shi, Guang-Can Guo
We report the generation of a type-I multimode two-photon state on a rubidium D line (780 nm) using periodically poled KTiOPO crystals. With a degenerate optical parametric…
