摘要本文提出一种用参量下转换光子对偏振纠缠的特性实现的量子密码术实验方案，同Ｅｋｅｒｔ提出的基于参量下转换光子对时空纠缠特性的实验方案相比，本方案省掉了两个复杂的Ｍａｃｈ－Ｚｅｎｈｄｅｒ干涉仪和两个昂贵的单光子探测器，简化了系统装置。 We propose a novel Quantum Cryptography Experimental scheme using polarization entangled photon pairs generated by Optical Parametric Down Conversion. Compared with Ekert′s scheme based on space time entangled photo pairs, our scheme spares two complex Mach Zehnder interferometer and two expensive single photon detector,thus simplifies the experimental setup.
