Reaching the Limits of Ground-State Metrology with Many-Body Probes
Erik L. André, Víctor Izquierdo, Ricard Puig +2
We investigate the physical requirements to reach the ultimate limits of ground-state metrology -- i.e., the estimation of an unknown parameter of an -body Hamiltonian via m…

Dynamical, thermal, and ground-state multiparameter quantum metrology: Fundamental limits and their attainability in magnetometry
Riccardo Pedroni, Víctor Izquierdo, Advay Burte +3
We consider the simultaneous estimation of multiple parameters in Hamiltonians of the form , where encodes the unknown parameters and $H…

Thermodynamic Networks: Harnessing Non-Equilibrium Steady States for Computation
Patryk Lipka-Bartosik, Gianmichele Blasi, Javier Lalueza Puértolas +3
We introduce thermodynamic networks, a general framework for autonomous, physics-based computation using non-equilibrium steady states. These networks are modeled as a collection o…
