Convergence rates of Sum-of-Hermitian-Squares Hierarchies for the Pauli algebra
Ali Almasi, Dávid Bugár, Cambyse Rouzé +1
Moment/Sum-of-Hermitian-Squares relaxations for noncommutative polynomial optimization problems have become an important tool for analyzing problems within quantum theory. Despite…

Asymptotic equipartition property of subadditive multipartite entanglement measures on pure states
Dávid Bugár
We investigate the asymptotic equipartition property (AEP) in the context of multipartite entanglement measures on pure states. Specifically, we formulate AEP for subadditive entan…

Interpolating between Rényi entanglement entropies for arbitrary bipartitions via operator geometric means
Dávid Bugár, Péter Vrana
The asymptotic restriction problem for tensors can be reduced to finding all parameters that are normalized, monotone under restrictions, additive under direct sums and multiplicat…
