Riccati方程与退相干问题
Riccati equation and the problem of decoherence
摘要：
利用分块算符矩阵理论研究了单个量子比特的问题。我们将在Riccati算子方程和获得所讨论的量子比特的精确约化动力学的可能性之间建立联系。讨论了旋转磁场中与外界环境耦合的半自旋粒子模型。我们表明，以这种方式定义的模型可以减少到一个时间无关的问题。
英文摘要：
The block operator matrix theory is used to investigate the problem of a single qubit. We will establish a connection between the Riccati operator equation and the possibility of obtaining an exact reduced dynamics for the qubit in question. The model of the half spin particle in the rotating magnetic field coupling with the external environment is discussed. We show that the model defined in such a way can be reduced to a time independent problem.
