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
