    "abstract": "We show how to improve the efficiency for preparing Bell states in coupled\ntwo quantum dots system. A measurement to the state of driven quantum laser\nfield leads to wave function collapse. This results in highly efficiency\npreparation of Bell states. The effect of decoherence on the efficiency of\ngenerating Bell states is also discussed in this paper. The results show that\nthe decoherence does not affect the relative weight of $|00\u003e$ and $|11\u003e$ in the\noutput state, but the efficiency of finding Bell states.",
