摘要: 提出了一种基于交叉克尔非线性效应产生四光子偏振态簇态的方案,与其他产生四光子簇态的方案比较,该方案引入宇称门的思想和用到基于零差探测的非破坏测量方法,使得该方案在实验上更易于操作及实现.Abstract: We propose a scheme for generating four-photon polarization-entangled cluster states based on the cross-Kerr nonlinear interaction between field-modes. Compared with other schemes, our scheme introduces the idea of parity gate and uses the non-destructive measurement method based on homodyne detection, which is easier to implement in experiment.
