Upper bounds for relative entropy of entanglement based on convex hull approximation

2019 · arXiv (Cornell University)

Quantifying entanglement for multipartite quantum state is a crucial task in many aspects of quantum information theory. Among all the entanglement measures, relative entropy of entanglement $E_{R}$ is an important quantity due to its clear …

Neural networks for quantum inverse problems

2022 · New Journal of Physics

Abstract Quantum inverse problem (QIP) is the problem of estimating an unknown quantum system from a set of measurements, whereas the classical counterpart is the inverse problem of estimating a distribution from a set of …

Tapping into Permutation Symmetry for Improved Detection of k-Symmetric Extensions

2023 · Entropy

Symmetric extensions are essential in quantum mechanics, providing a lens through which to investigate the correlations of entangled quantum systems and to address challenges like the quantum marginal problem. Though semi-definite programming (SDP) is a …
