我们给出了对连续波(CW)高斯场进行非高斯测量所获得的状态的一般分析。连续波高斯场的一般多模态完全由场的随时间变化的均值和方差以及场的二次协方差来刻画。我们提出了一种从这些信息中提取特定时间输出模式下的探测和量子态约化结果的一般理论。该理论被应用于从连续波压缩光束中产生具有单光子和薛定谔猫态的传输光脉冲的方案。
We present a general analysis of the state obtained by subjecting a continuous-wave (cw) Gaussian field to non-Gaussian measurements. The generic multimode state of a cw Gaussian field is fully characterized by the time dependent mean values and variances and the two-time covariances of the field quadrature variables. We present a general theory to extract from this information the results of detection and quantum state reduction within specific temporal output modes. The formalism is applied to schemes for heralded production of propagating light pulses with single photon and Schr\"odinger kitten states from a cw squeezed beam of light.
