我们在一个单一的时空模式产生脉冲，双模压缩态，平均光子数高达20。我们直接测量两种模式之间的光子数相关性与过渡边缘传感器高达80光子每模式。这大致对应于6400的状态维度。我们实现了64%的检测效率，在技术上至关重要的电信制度，并证明了我们的测量的高品质，预示着非经典分布高达50个光子每脉冲和计算的相关函数高达40阶。
We generate pulsed, two-mode squeezed states in a single spatiotemporal mode with mean photon numbers up to 20. We directly measure photon-number correlations between the two modes with transition edge sensors up to 80 photons per mode. This corresponds roughly to a state dimensionality of 6400. We achieve detection efficiencies of 64% in the technologically crucial telecom regime and demonstrate the high quality of our measurements by heralded nonclassical distributions up to 50 photons per pulse and calculated correlation functions up to 40th order.
