Abstract :
In this work, the entanglement of a superposition of bipartite qubit coherent states
with non-phased coherent parameters is studied. We use Generalized-concurrence as the
measure to quantify the entanglement and drive analytical results in terms of the
effective parameters involved. Analyzing the results, we conclude that such states may
attain maximum entanglement or no entanglement at all, depending on the choice of the
parameters involved.
