Optimal Heisenberg-style bounds for the average performance of arbitrary phase estimates
Dominic W. Berry, Michael J. W. Hall, Marcin Zwierz +1
The ultimate bound to the accuracy of phase estimates is often assumed to be given by the Heisenberg limit. Recent work seemed to indicate that this bound can be violated, yielding…

Nonlocal signaling in the configuration space model of quantum-classical interactions
Michael J. W. Hall, Marcel Reginatto, C. M. Savage
When interactions are turned off, the theory of interacting quantum and classical ensembles due to Hall and Reginatto is shown to suffer from a nonlocal signaling effect that is ef…
