| Abstract: | 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. |

| Keywords: | quantum state positive-operator valued measures(POVM) symmetric states |
