Abstract

Recently a nonclassicality indicator is introduced which is based on the interference of quantum states in phase space quantum mechanics. It is applied for some real distribution functions. Kenfack and Życzkowski had also defined a non classicality indicator based on the amount of negativity in Wigner function. Here, we applied these nonccassicality indicators for entangled state of two eigenstate of Harmonic oscillator in the Wigner, Husimi and Rivier representations. The maximum of nonclassicality indicator is happen for pseudo bell states and the behavior of nonclassicality indicators are compared with the entanglement of formation.
