Efficient generation of non-classical photon pairs in a hot atomic ensemble Download: 597次
Abstract
We demonstrate the generation of non-classical photon pairs in a warm Rb 87 atomic vapor cell with no buffer gas or polarization preserving coatings via spontaneous four-wave mixing. We obtain the photon pairs with a 1/e correlation time of 40 ns and the violation of Cauchy–Schwartz inequality by a factor of 23 ± 3 . This provides a convenient and efficient method to generate photon pair sources based on an atomic ensemble.
