摘要

实验实现了一种基于偏振自由度的光子概率量子控相门。这个双量子位门对目标光子施加/spl phi/的相移，条件是控制光子的偏振。它的主要架构遵循J. L. CT . Brien等人的方法，他们使用所有的逻辑编码。

Applications of a controlled phase gate for photons

A probabilistic quantum controlled-phase gate for photons operating on the polarization degree of freedom is experimentally implemented. This two qubit gate applies a phase shift of /spl phi/ to a target photon, conditioned on the polarization of a control photon. Its principal architecture follows the approach of J. L. CT Brien et al. who uses however all logic encoding.
