Two convergent NPA-like hierarchies for the quantum bilocal scenario
Marc-Olivier Renou, Xiangling Xu, Laurens T. Ligthart
Characterising the correlations that arise from locally measuring a single part of a joint quantum system is one of the main problems of quantum information theory. The seminal wor…
Entanglement-swapping in generalised probabilistic theories, and iterated CHSH games
Lionel J. Dmello, Laurens T. Ligthart, David Gross
While there exist theories that have states "more strongly entangled" than quantum theory, in the sense that they show CHSH values above Tsirelson's bound, all known examples of su…
The polarization hierarchy for polynomial optimization over convex bodies, with applications to nonnegative matrix rank
Martin Plávala, Laurens T. Ligthart, David Gross
We construct a convergent family of outer approximations for the problem of optimizing polynomial functions over convex bodies subject to polynomial constraints. This is achieved b…
