摘要
量子纠缠源是量子通信和量子计算的基础,实现隐形传态最重要的关键和难点是制备高纠缠度的、稳定高效的EPR光子纠缠源。系统综述了国内外采用非线性光学频率变换制备纠缠光子源的实验方法以及实验研究的最新进展。
Entangled photon sources are the basis of the quantum communication and quantum computation. To produce the high-flux, stable, effective source of EPR entangled photon is essential for realizing the quantum teleportation. The mechanisms and conventional techniques for fabricating the entangled photon sources are presented and the latest progresses of the experimental investigations of the entangled photon sources are described.
