Abstract

The evolution of the conduction-band spins of quantum dots was studied. An analytical solution and its Schmidt decomposition for the equivalent-neighbor model was obtained. The solution was applied to the study of bipartite entanglement in quantum dot systems with arbitrary numbers of dots and their excitations. Results indicated that the perfect maximally entangled states could be generated in systems of up to six dots with a single dot initially excited. A monotonic decrease of entanglement was observed with increase in total number of dots in a system with a fixed number of excitations.
