- Abstract
In this paper, we have analyzed the entanglement and nonclassicality of two-mode superposition coherent states based on two coherent states shifted in phase by π/2. Here, the relative phase of the superposition will be taken equal to the phase shift between the two coherent states i.e. φ = π/2. Entanglement-sensitivity is investigated and it was found that out of four, only one state is maximally entangled. Moreover, it is also revealed that the considered states have stronger nonclassical features than those of even-odd entangled coherent states.
