Quantum interference in the Kirkwood-Rihaczek representation

摘要

We discuss the Kirkwood-Rihaczek phase space distribution and analyze a whole class of quasi-distributions connected with this function. All these functions have the correct marginals. We construct a coherent state representation of such functions, discuss which operator ordering corresponds to the Kirkwood-Rihaczek distribution and their generalizations, and show how such states are connected to squeezed states. Quantum interference in the Kirkwood-Rihaczek representation is discussed.
