Semidefinite hierarchies for diagonal unitary invariant bipartite quantum states
Jonas Britz, Monique Laurent
We investigate questions about the cone of separable bipartite states, consisting of the Hermitian matrices acting on that can be…

Moment-sos and spectral hierarchies for polynomial optimization on the sphere and quantum de Finetti theorems
Alexander Taveira Blomenhofer, Monique Laurent
We revisit the convergence analysis of two approximation hierarchies for polynomial optimization on the unit sphere. The first one is based on the moment-sos approach and gives sem…

An Overview of Convergence Rates for Sum of Squares Hierarchies in Polynomial Optimization
Monique Laurent, Lucas Slot
In this survey we consider polynomial optimization problems, asking to minimize a polynomial function over a compact semialgebraic set, defined by polynomial inequalities. This mod…
