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, |>=μ|α>|β>+λ|α>|δ>+ |γ>|β>+|γ>|δ>, constructed by linearly independent coherent states with real parameters when <α|γ>=<β|δ>. This is a further generalization of the classified nonorthogonal states discussed in Ref. Physics Letters A 291, 73-76 (2001).
