SZFI SeminarSzalay SzilárdHUN-REN Wigner RCP SZFIAlternatives of entanglement
depth and metrological entanglement criteriaTuesday, 3 June 2025, 10:00, KFKI
Campus, Bldg. 1, 2nd floor, Conference RoomWe show that the Quantum Fisher
Information in quantum metrology, which can be bounded from below in
experiments, provides a lower bound on the Average Size of Entangled
Subsystems. This is a particular case of a new kind of multipartite
entanglement criterion, restricting the relative weights of the pure states
of different average sizes of entangled subsystems in the mixed state. We
illustrate the strength of this convex criterion and compare it to the
original metrological entanglement criterion given by the entanglement depth.
