Abstract

A study was conducted to show how maximally entangled Bell and Greenberger-Horne-Zeilinger (GHZ) states can be generated using the optically driven resonant transfer of excitons between quantum dots. Selective Bell and GHZ pulses have been identified by an approximate, yet accurate, analytical approach which should prove a useful tool when designing experiments. Exact numerical calculations confirm the existence of such π/2 pulses for the generation of maximally entangled states in coupled dot systems.
