摘要
Using the coherent state representation of the Wigner operator, the Wigner function for the photon-added-even and odd coherent state (PAEOCS) is obtained. In terms of the variations of the Wigner function with the complex parameter a in the phase space, the non-classical properties of the PAEOCS are discussed. It is found that the PAEOCS always exhibits the nonclassical properties, and the photon-added even (or odd) coherent state exhibits the non-classical properties more easily when m is odd (or even). By virtue of the marginal distributions of the Wigner function for the PAEOCS, we illuminate the physical meaning of the Wigner function. Finally, based on the intermidate coordinate-momentum presentation the quantum tomogram function for the PAEOCS is obtained.
