摘    要:证明在含有克尔介质的双光子J-C模型系统中通过对原子的测量可以制备“薛定谔猫态”。选择适当的测量时间,原子初态及非线性系数,即可产生偶相干态,奇相干态和Y-S相干态。

关 键 词:薛定谔猫态  克尔非线性介质  J-C模型  量子光学

Abstract:We have proven that the Schrodinger cat states can be generated by conditional measurement on the atom in the Jaynes Cumming model with a Kerr like medium. The special states such as even coherent states, odd coherent state and Yurke Stoler coherent state may be aqcuired by further choosing some suitable parameters, such as the time of measurement, initial state of the atom, and Kerr nonlinear constant. The sub poisson distribution can be revealed under the high field approximation (n>>1) only in the existence of Kerr medium.
Keywords:Schrodinger cat state  Kerr medium  quantum measurement
