چکیده
Pair coherent state, is a state of a two-mode radiation field that is known as a state with  non-gaussian
wave function. In this paper, study on the pair coherent state, we notice that with superposition of two first terms of
this states, one two-qubits formed. Because of the importance of two-qubits in theory of quantum entanglement, with
two different measures with the title of concurrence and D-concurrence, we have studied the amount of entanglement
and discussed its details. At the end, we describe these measures for pair coherent states as a function of the amplitude
of the SU(2) coherent states.
