Generation of Entanglement for Coherent Excitonic States in Coupled Quantum Dots in a Microcavity

We investigate the generation of entanglement of coherent excitonic states in coupled quantum dots placed in a cavity by meaning of the state preparation fidelity [Nature （London） 404 （2002） 256; Phys. Rev. A 65 （2002） 012107; J. Uffink, Phys. Rev. Lett. 88 （2002） 230406.] The effect of the number o...

Description
Summary:We investigate the generation of entanglement of coherent excitonic states in coupled quantum dots placed in a cavity by meaning of the state preparation fidelity [Nature （London） 404 （2002） 256; Phys. Rev. A 65 （2002） 012107; J. Uffink, Phys. Rev. Lett. 88 （2002） 230406.] The effect of the number of excitons and the coherent intensity ｜α｜ of the cavity field on the entanglement is also studied.
