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…
Quantum sequential parameter testing
Simon Morelli, Ricard Ravell Rodríguez, John Calsamiglia +3
Sequential strategies in hypothesis testing use a variable number of measurement rounds, allowing a decision to be made as soon as the observed data provide a prescribed level of e…
Quantum-Enhanced Zero-Error Communication and Storage under Positional Uncertainty
Arnau Diebra, David González-Lociga, Mark Hillery +2
Permutation channels model communication and storage scenarios in which the positional identity of the physical carriers is partially or completely lost, so that the transmitted in…
Sequential analysis in a continuous spin-noise quantum sensor
Elisabet Roda-Salichs, Giulio Gasbarri, Antoni Alou +5
Many control and detection applications require real-time analysis of signals from sensors, in order to quickly and accurately act upon events revealed by the sensors. Such signal…
Quantum Advantage in Identifying the Parity of Permutations with Certainty
Arnau Diebra, Santiago Llorens, David González-Lociga +4
We establish a sharp quantum advantage in determining the parity (even/odd) of an unknown permutation applied to any number of particles. Classically, this is impossible…
