Research output: Contribution to journalArticlepeer-review


We study the transport of many partially distinguishable and possibly interacting particles under the action of repeated projective measurements on a target space and investigate how the particles' interference affects the mean first-detection time. We contrast the detection of exactly n versus at least n particles, explain divergences in the mean first-detection time through spectral properties of the generating evolution operator, and illustrate our findings by an example.
