我们发展了一个多光子多模线性光学网络(LONS)中与广义Pauli算符相关的互无偏基中的量子相干的访问理论。我们展示了一种在多光子离子中构造互补泡利测量的方法，并建立了一种在不考虑玻色子采样的计算复杂性的情况下评估其光子测量统计的理论。这一理论将单光子离子互补性质的表征推广到了凸顶扩展的多光子离子。它使我们能够利用互补的泡利测量来检测量子性质，如纠缠，这揭示了两粒子多光子离子中模间纠缠的物理意义。
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.
