摘　　要：研究了二项式态光场和负二项式态光场与耦合超导量子比特相互作用下的超导电流的时间演化规律.研究结果显示:在确定的二项式态或负二项式态光场中,耦合超导量子比特的初始量子态对穿过自身的超导电流的动力学行为几乎没有影响;但光场的量子态,尤其是光场参数对超导电流的动力学行为具有调控作用.因此,通过测量超导量子比特的输出电流,能够探测量子光场的统计性质.The time evolution laws of superconducting current under the interaction between superconducting qubits and light field of binomial states and negative binomial states has been studied.The results show that the initial quantum state of coupled superconducting qubit has almost no influences on the dynamical behavior of superconducing current which passed through it in the determining light field of binomial states and negative binomial states.However,the quantum state of light field,especially the light field parameters,can regulate the dynamical behavior of superconducing current.So,by measuring the output current of superconducting qubit,we are able to detect the statistical nature of quantum light field.
