Separability gap and large deviation entanglement criterion
Jakub Czartowski, Konrad Szymański, Bartłomiej Gardas +2
For a given Hamiltonian on a multipartite quantum system, one is interested in finding the energy of its ground state. In the separability approximation, arising as a nat…

Entanglement properties of multipartite informationally complete quantum measurements
Jakub Czartowski, Dardo Goyeneche, Karol Życzkowski
We analyze tight informationally complete measurements for arbitrarily large multipartite systems and study their configurations of entanglement. We demonstrate that tight measurem…
