Efficient quantum memory for heralded single photons generated by cavity-enhanced spontaneous parametric downconversion
Yu-Chih Tseng, Yan-Cheng Wei, Ying-Cheng Chen
We interface a spontaneous parametric down conversion (SPDC) crystal and a cold atomic ensemble and demonstrate a highly efficient quantum memory through polarization-encoded singl…

Effect of laser frequency fluctuation on the decay rate of Rydberg coherence
Bongjune Kim, Ko-Tang Chen, Chia-Yu Hsu +8
The effect of electromagnetically induced transparency (EIT) combined with Rydberg-state atoms provides high optical nonlinearity to efficiently mediate the photon-photon interacti…
