Periodic conditional measurements on a photonic chip
Xuan Chen, Ruo-Yu Yin, Xiao-Wen Shang +10
Quantum measurements not only extract information but also reshape quantum evolution through measurement backaction. Here, we investigate periodic conditional measurements, in whic…
Quantum Walks: First Hitting Times with Weak Measurements
Tim Heine, Eli Barkai, Klaus Ziegler +1
We study the first detected recurrence time problem of continuous-time quantum walks on graphs. While previous works have employed projective measurements to determine the first re…
First Hitting Times on a Quantum Computer: Tracking vs. Local Monitoring, Topological Effects, and Dark States
Qingyuan Wang, Silin Ren, Ruoyu Yin +3
We investigate a quantum walk on a ring represented by a directed triangle graph with complex edge weights and monitored at a constant rate until the quantum walker is detected. To…
Randomly repeated measurements on quantum systems: Correlations and topological invariants of the quantum evolution
K. Ziegler, E. Barkai, D. Kessler
Randomly repeated measurements during the evolution of a closed quantum system create a sequence of probabilities for the first detection of a certain quantum state. The related di…
