From dynamical to steady-state many-body metrology: Precision limits and their attainability with two-body interactions
Ricard Puig, Pavel Sekatski, Paolo Andrea Erdman +3
We consider the estimation of an unknown parameter via a many-body probe. The probe is initially prepared in a product state and many-body time-independent interactions enhance…
Escaping the Shadow of Bell's Theorem in Network Nonlocality
Maria Ciudad Alañón, Emanuel-Cristian Boghiu, Paolo Abiuso +1
The possibility of nonclassicality in networks unrelated to Bell's original eponymous theorem has recently attracted significant interest. Here, we identify a sufficient condition…
Fundamental limits of metrology at thermal equilibrium
Paolo Abiuso, Pavel Sekatski, John Calsamiglia +1
We consider the estimation of an unknown parameter through a quantum probe at thermal equilibrium. The probe is assumed to be in a Gibbs state according to its Hamiltonian $H_θ…
