我们在实验上演示了在时间域中光束之间的爱因斯坦-蒲多尔斯基-罗森(EPR)关联的产生和表征。相关光束由两个独立的连续波光参量振荡器和一个半分束器产生。我们使用持续时间为$T$的平方时间滤波器定义时间模式，并对生成的状态进行时间分辨测量。我们观察到与EPR相关的时间域中相关共轭变量之间的相关性。我们的方案可推广到定义在时间域中的非高斯态的连续变量量子隐形传态，如类薛定谔猫态。
We experimentally demonstrate creation and characterization of Einstein-Podolsky-Rosen (EPR) correlation between optical beams in the time domain. The correlated beams are created with two independent continuous-wave optical parametric oscillators and a half beam splitter. We define temporal modes using a square temporal filter with duration $T$ and make time-resolved measurement on the generated state. We observe the correlations between the relevant conjugate variables in time domain which correspond to the EPR correlation. Our scheme is extendable to continuous variable quantum teleportation of a non-Gaussian state defined in the time domain such as a Schr\"odinger cat-like state.
