Here, we quantify the amount of quantum backflow for arbitrary momentum distributions, paving the way towards its experimental verification. We give examples of backflow in gravitational and harmonic potential, and discuss experimental procedures required for the demonstration using atomic gravimeters. Such an experiment would show that the probability of finding a free falling particle above initial level could grow for suitably prepared quantum state with most momentum downwards. © Revista de Internet, Derecho y Politica 2021. | Source Title: | Quantum | URI: | https://scholarbank.nus.edu.sg/handle/10635/233793 | ISSN: | 2521-327X | DOI: | 10.22331/q-2021-01-11-379 | Rights: | Attribution 4.0 International |
