研究了置于一个单模驻波光腔中的两个二能级原子，通过利用测量场的正交分量的方法定位这两个原子位置的情况。发现在不考虑腔损耗的条件下，利用此方法即可很好地定位两原子的位置。若考虑腔损耗时，通过将测量所输出的信号反馈回光腔中的方法可降低由腔损耗所导致两原子定位能力的损害程度。

We have investigated the localization of the two atoms passing through a standing wave in an optical cavity by measuring the field quadrature. It was found that the localization of the two atoms can be better preserved in the absence of the damping of cavity. If the damping of cavity is taken into account, the compromise of atomic-position localization resulting from the damping of cavity can be decreased by feedi...
