Abstract

General method and some skill are introduced in this paper.Taking coherent state as example，an orthogonal state is constructed based on the creation operator.Three properties of the orthogonal state，including mean photon number，photon number distribution and Wigner function，are studied.Moreover，we compare these properties with those of original coherent state and photon-added coherent state.

Key words： pure quantum state; orthogonalization; orthogonal state; coherent state
