Temporal Interference from Topological Transitions in Monitored Quantum Dynamics
Qingyuan Wang, Ruoyu Yin, Eli Barkai
The paper studies how stroboscopic measurements of a quantum system reveal temporal interference patterns that arise when a topological winding number changes, creating dark states…

Resonances of recurrence time of monitored quantum walks
Ruoyu Yin, Qingyuan Wang, Sabine Tornow +1
The recurrence time is the time a process first returns to its initial state. Using quantum walks on a graph, the recurrence time is defined through stroboscopic monitoring of the…

Restart uncertainty relation for monitored quantum dynamics
Ruoyu Yin, Qingyuan Wang, Sabine Tornow +1
We introduce a novel time-energy uncertainty relation within the context of restarts in monitored quantum dynamics. Initially, we investigate the concept of ``first hitting time''…
