摘要
理论分析并实验制备了795 nm两组份偏振纠缠光场。当分析频率为1.8~6.5 MHz时, 归一化的斯托克斯算符的量子关联噪声小于1, 得到了两组份偏振纠缠态; 当分析频率大于3 MHz时, 关联噪声达到0.5左右。该非经典光源可应用于未来的量子存储, 并且可能用于实现量子通道和量子节点之间、两个量子节点之间的纠缠以及量子态的传输。
Abstract
Bipartite polarization entangled optical fields are theoretically analyzed and experimentally prepared. When the analysis frequency is 1.8-6.5 MHz, the normalized quantum correlation noise of Stokes operator is below 1, where the bipartite polarization entangled state is obtained. When the analysis frequency is above 3 MHz, the correlation noise reaches 0.5. This non-classical light source can be applied in quantum memory in future and to realizing the entanglement and quantum state transfer between the quantum channel and quantum node or between two quantum nodes.
