Maximal Entanglement of Two-qubit States Constructed by Linearly Independent Coherent States

Abstract

In this paper, we find the necessary and sufficient condition for the maximal entanglement of the state, $|\psi >=\mu |\alpha >|\beta >+\lambda |\alpha >|\delta >+\rho |\gamma >|\beta >+\nu |\gamma >|\delta >,$ constructed by linearly independent coherent states with \emph{real parameters} when $<\alpha |\gamma >=<\beta |\delta >$. This is a further generalization of the classified nonorthogonal states discussed in Ref. Physics Letters A {\bf{291}}, 73-76 (2001).
