| Abstract: | 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. |
