Abstract

We analyze generation of maximally entangled states (EPR and W states) of the conduction-band electron spins in systems of an arbitrary number of semiconductor quantum dots under equivalent-neighbor interactions mediated by a single-mode cavity field. We show that the perfect EPR states in bipartite systems and perfect W states in multipartite ones can only be generated in systems of up to six and four dots, respectively, with single or, equivalently, all dots except one excited.
