Iterative optimization in quantum metrology and entanglement theory using semidefinite programming
Árpád Lukács, Róbert Trényi, Tamás Vértesi +1
We discuss efficient methods to optimize the metrological performance over local Hamiltonians in a bipartite quantum system. For a given quantum state, our methods find the best lo…

Activation of metrologically useful genuine multipartite entanglement
Róbert Trényi, Árpád Lukács, Paweł Horodecki +3
We consider quantum metrology with several copies of bipartite and multipartite quantum states. We characterize the metrological usefulness by determining how much the state outper…
