摘    要:
We show that the Susskind-Glogower phase state is a limiting case of a kind of SU(1,1) coherent states. By analogy, based on the bipartite entangled state representation (ESR) we demonstrate that an appropriate SU(1,1) coherent state composed of the two-mode unitary phase operator e^i also leads to a new phase state in two-mode Fock space, e^i is diagonalized in the ESR.
