Entangled Coherent States
- Authors: Deepak and Arpita Chatterjee
- Abstract summary: We obtain Mandel's $Q_ml$, antibunching $d_hl-1$, Subpoissioning photon statistics $D_h(l-1)$ and Squeezing $S(l)$ for the states obtained.
Also the fourth or last criterion $S(l)$ gives non-classicality for lower order as well as higher order.

- 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.

A set of maximally fermion-boson entangled Bell super-coherent states is introduced.
A superposition of these states with separable bosonic coherent states is represented by points on the super-Bloch sphere.
Entanglement of bosonic and fermionic degrees of freedom in these states is studied by using displacement bosonic operator.
