Formula for Computation of Wigner Function for Two Mode Quantized Electromagnetic Field and its Application in Detection of Nonclassicality

Sushamana Sharma | J.K. Sharma

Abstract: An expression for Wigner function is obtained for a density matrix which is expressible in photon number state representation. The result is then applied to detect the presence of nonclassicality. A conclusion is drawn that the magnitude of most negative value of Wigner function decreases with the decrement in degree of entanglement.

Keywords: Wigner function, nonclassicality, entangled states, two mode electromagnetic field, negativity of states
