研究了SU（2）相干态描述的量子偏振光的几何相位。这是通过使用量子干涉来揭示的。利用量子化的Stokes参数构造了SU（2）相干态。量子干涉是由演化算符安排的，演化算符由法拉第和克尔效应的双折射启发的哈密顿量实现。几何相位由相干态路径积分给出。特别地，通过考虑共振哈密顿量，从由几何相位和动力学相位组成的总因子中提取几何相位。这种提取形成了检测几何相位的实验方法的基础。
The geometric phase is studied for quantum polarized light described by an SU(2) coherent state. This is revealed by using quantum interference. The SU(2) coherent state is constructed from the quantized Stokes parameters. The quantum interferometry is arranged by the evolution operator implemented by the Hamiltonian inspired from the birefringence of the Faraday and Kerr effect. The geometric phase is given by the coherent state path integral. In particular, by considering a resonant Hamiltonian, the geometric phase is extracted from the total factor that consists of both geometric and dynamical phases. This extraction forms the basis of an experimental way to detect the geometric phase.
