中文摘要：
利用自发拉曼散射过程,在87 Rb冷原子系综中进行了关联光子对的制备。实验结果表明：存储时间为1μs时,关联光子的二阶关联函数g（2）可达到84,表明光子对之间存在着很强的非经典关联。另外,在激发率为1.5%时,对anti-Stokes光子的宣布式单光子统计特性α进行了测量,当存储时间小于24μs时,α保持在0.23附近。该工作为冷原子系综中纠缠光子对的产生提供了实验基础。
英文摘要：
The generation of correlation photon pairs was implemented in cold 87 Rb ensemble based on Spon- taneous Raman scattering process, which demonstrates that the second order intensity cross-correlation functions g（2） can be up to 84 on condition that the storage time r is equal to lμs, indicating the strong non- classic correlation features among photon pairs. Besides,based on the excitation rate of 1.5%, the meas- urement of a, heralded single photon statistical property of anti-Stokes photons, was carried out, which shows that the value of a is always near to 0.23 while the storage time increased from 0 to 24 μs. It is be- lieved that this work will pave the way for the generation of entanglement photons in atomic ensemble.
