摘要:

我们创建独立的,同步的单光子源与内置的量子存储器的基础上两个远程冷原子合奏。同步的单光子被用来证明纠缠的有效产生。由此产生的纠缠光子对违反贝尔不等式5个标准偏差。我们的同步单光子具有25 ns的长相干时间和有效的纠缠产生,作为可扩展的线性光学量子信息处理的理想构建块。

英文摘要:

We create independent, synchronized single-photon sources with built-in quantum memory based on two remote cold atomic ensembles. The synchronized single photons are used to demonstrate efficient generation of entanglement. The resulting entangled photon pairs violate a Bell's Inequality by 5 standard deviations. Our synchronized single photons with their long coherence time of 25 ns and the efficient creation of entanglement serve as an ideal building block for scalable linear optical quantum information processing.
