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…
Temporal Interference from Topological Transitions in Monitored Quantum Dynamics
Qingyuan Wang, Ruoyu Yin, Eli Barkai
Quantum interference is conventionally associated with the coherent superposition of alternative paths. We uncover a temporal form of interference in repeatedly monitored quantum s…
Resonances, Recurrence Times and Steady States in Monitored Noisy Qubit Systems
Shuanger Ma, Sabine Tornow, Eli Barkai
We study non-equilibrium steady states and recurrence times in noisy, stroboscopically monitored qubit systems using complete measurements. In the noiseless limit, recurrence times…
Sokoban Random Walk: A Trapping Perspective
Prashant Singh, Eli Barkai, David A Kessler
We study caging/trapping in Sokoban-type models, featuring a random walker moving through a disordered medium of obstacles and capable of pushing some obstacles blocking its path.…
Transition in Splitting Probabilities of Quantum Walks
Prashant Singh, David A. Kessler, Eli Barkai
We investigate the splitting probability of a monitored continuous-time quantum walk with two targets and show that, in stark contrast to a classical random walk, it exhibits a non…
The Thermodynamic Limit of Extreme First-Passage Times
Talia Baravi, Eli Barkai
The statistics of the slowest first-passage time among a large population of searchers is crucial for determining the completion time of many stochastic processes. Classical ex…
Sokoban Random Walk: From Environment Reshaping to Trapping Crossover
Prashant Singh, David A. Kessler, Eli Barkai
We study the dynamics of a Sokoban random walker moving in a disordered medium with obstacle density . In contrast to the classic model of de Gennes with static obstacles that e…
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…
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…
Solutions of first passage times problems: a biscaling approach
Talia Baravi, David A. Kessler, Eli Barkai
We study the first-passage time (FPT) problem for widespread recurrent processes in confined though large systems and present a comprehensive framework for characterizing the FPT d…
Rare Events and Single Big Jump Effects in Ornstein-Uhlenbeck Processes
Alberto Bassanoni, Alessandro Vezzani, Eli Barkai +1
Even in a simple stochastic process, the study of the full distribution of time integrated observables can be a difficult task. This is the case of a much-studied process such as t…
A tale of three approaches: dynamical phase transitions for weakly bound Brownian particles
Lucianno Defaveri, Eli Barkai, David A. Kessler
We investigate a system of Brownian particles weakly bound by attractive parity-symmetric potentials that grow at large distances as , with . The probabi…
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…
Fractionally Quantized Recurrence Detection Times in Monitored Quantum Many-Body Systems
Quancheng Liu, Sabine Tornow, David A. Kessler +1
Recurrence time quantifies the duration required for a physical system to return to its initial state, playing a pivotal role in understanding the predictability of complex systems…
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''…
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…
Solution of the Fokker-Planck equation with a logarithmic potential
A. Dechant, E. Lutz, E. Barkai +1
We investigate the diffusion of particles in an attractive one-dimensional potential that grows logarithmically for large using the Fokker-Planck equation. An eigenfunction e…
