Abstract

We compare the lower and higher order non-classicality of a class of the photon-added Bell-type entangled coherent states (PBECS) got from Bell-type entangled coherent states using creation operators. We obtained lower and higher order criteria namely Mandel's Q_m^l, antibunching d_h^l-1, Subpoissioning photon statistics D_h(l-1) and Squeezing S(l) for the states obtained. Further we observe that first three criteria does not gives non-classicality for any state and higher order criteria gives very high positive values for all values of parameters. Also the fourth or last criterion S(l) gives non-classicality for lower order as well as higher order.
