Research Abstract

We investigate an analytical solution for a two-qubit field system in the dispersive regime with a
reservoir. We analyze the influence of the phase damping on the Wigner function and the phase
properties. We found that the phase damping destroys the phase probability of the global system for
the coherent state and even coherent state. The phase damping leads to decay of the Wigner function
for the coherent state.
