摘　　要：依靠单光子来表示量子态和多轨光学网络来进行幺正变换,我们针对普适的、可编程的量子状态区分给出了一套方案,能对两个未知三维量子态给出最优化的明确分辨.With a single-photon representation of the quantum states and a multi-rail optical network for perfoming the unitary transformation.we give a scheme for an optical implementation of the universal programmable quantum state discriminator that unambiguously discriminates between two unknown states with optimal probability of success.
