Restart expedites quantum walk hitting times
Classical first-passage times under restart are used in a wide variety of models, yet the
quantum version of the problem still misses key concepts. We study the quantum hitting time …

Instability in the quantum restart problem
Repeatedly monitored quantum walks with a rate 1/τ yield discrete-time trajectories which
are inherently random. With these paths the first-hitting time with sharp restart is studied. We …

Quantum dynamics under continuous projective measurements: Non-Hermitian description and the continuum-space limit
The problem of the time of arrival of a quantum system in a specified state is considered in
the framework of the repeated measurement protocol and in particular the limit of continuous …

Measurement-induced quantum walks on an IBM quantum computer
We study a quantum walk of a single particle that is subject to stroboscopic projective

First detected arrival of a quantum walker on an infinite line
The first detection of a quantum particle on a graph is shown to depend sensitively on the
distance ξ between the detector and initial location of the particle, and on the sampling time …

Unmonitored and monitored recurrence in single-photon quantum walks
XX Chen, YJ Wang, AN Zhang, Z Meng, QY Wu… - Physical Review A, 2024 - APS
Recurrence is an interesting property that describes whether the walker will eventually
return to the origin on infinite lattices in classical random walks. Since measurement …
