Neural Copula: A unified framework for estimating generic high-dimensional Copula functions

2022 · arXiv (Cornell University)

The Copula is widely used to describe the relationship between the marginal distribution and joint distribution of random variables. The estimation of high-dimensional Copula is difficult, and most existing solutions rely either on simplified assumptions …

Linear-optical four-dimensional Bell state measurement with the two-photon interference

2025 · Journal of the Optical Society of America B

We theoretically investigate the distinguishability of a set of mutually orthogonal four-dimensional Bell states of photon system in path degree of freedom using only linear optics, resorting to the two-photon interference. With quantum interference effect, …
