Abstract

A non classical and non Gaussian states become an essential need in quantum information processing theoretically and experimentally. In the present paper, the non classical and non Gaussian properties of superposed states exposure to photon addition and photon subtraction operations are described. The effect of adding and subtracting photons to multi-coherent state has a great interest in improving the features of the state. Furthermore, the photons added then subtracted multi-coherent states is more efficient than the opposite scenario.
