Abstract
The solution to the master equation obtained using the ket-vector representation of the density operator usually appears as the Kraus operator sum representation. Another useful form of such solutions is the time-dependent Wigner operator. We derive the time-dependent Wigner operator from these solutions by a direct and simple method. Application of this method is easy when any Kraus operator maps a coherent state into another coherent state.
