论文摘要
我们已经开发了一种理论，用于访问与多光子多模层线性光学网络（LONS）中与广义的Pauli算子相关的相互无偏基的量子相干。我们展示了一种在多光子lon中构建互补的Pauli测量的方法，并建立了一种评估其光子测量统计的理论，而无需处理玻色子采样的计算复杂性。该理论将单光子lon中的互补特性的表征扩展到采用凸够伸展的多光子隆。它使我们能够使用互补的Pauli测量值检测量子特性，例如纠缠，这揭示了两分部分多光子lons中模式之间纠缠的物理意义。
We have developed a theory for accessing quantum coherences in mutually unbiased bases associated with generalized Pauli operators in multiphoton multimode linear optics networks (LONs). We show a way to construct complementary Pauli measurements in multiphoton LONs and establish a theory for evaluation of their photonic measurement statistics without dealing with the computational complexity of Boson samplings. This theory extends characterization of complementary properties in single-photon LONs to multiphoton LONs employing convex-roof extension. It allows us to detect quantum properties such as entanglement using complementary Pauli measurements, which reveals the physical significance of entanglement between modes in bipartite multiphoton LONs.
