When does a particle arrive?
arXiv:2205.02219 · doi:10.22331/q-2023-03-30-968
Abstract
We compare the proposals that have appeared in the literature to describe a measurement of the time of arrival of a quantum particle at a detector. We show that there are multiple regimes where different proposals give inequivalent, experimentally discriminable, predictions. This analysis paves the way for future experimental tests.
