表征量子设备性能的可扩展技术对于创建大型量子网络和量子处理单元至关重要。量子信息处理的主要资源是纠缠。在这里，我们描述了完整的时间和空间特性的偏振纠缠光子产生的自发参量下转换使用增强的高速光学相机，Tpx3Cam。这种新的技术允许以最小的技术开销精确确定贝尔不等式参数，并为纠缠量子信息的空间分布提供新的表征方法。快速光学相机可能会在量子信息科学中产生多种应用，为量子实验的可扩展性开辟新的前景。
Scalable technologies to characterize the performance of quantum devices are crucial to creating large quantum networks and quantum processing units. Chief among the resources of quantum information processing is entanglement. Here we describe the full temporal and spatial characterization of polarization-entangled photons produced by Spontaneous Parametric Down Conversions using an intensified high-speed optical camera, Tpx3Cam. This novel technique allows for precise determination of Bell inequality parameters with minimal technical overhead, and for new characterization methods for the spatial distribution of entangled quantum information. The fast-optical camera could lead to multiple applications in Quantum Information Science, opening new perspectives for the scalability of quantum experiments.
