AbstractWe show how to improve efficiency in preparing Bell states in a coupled two-quantum-dot system, which was introduced by Quiroga and Johnson [Phys. Rev. Lett. 83, 2270 (1999)]. A measurement of the state of a driven quantum laser field leads to wave-function collapse. This results in the highly efficient preparation of Bell states. The effect of decoherence on the efficiency of generating Bell states is also discussed in this paper. The results show that decoherence does not affect the relative weight of \ 00 > and \ 11 > in the output state, but does affect the efficiency of finding Bell states.
