Nonequilibrium steady states induced by stochastic mid-circuit measurements and resets on a quantum computer
Jakob Murauer, Sabine Tornow, Gabriele Perfetto
Stochastic resetting has emerged as a versatile protocol to drive quantum many-body systems to non-equilibrium steady states by interspersing unitary dynamics with measurements and…
Monitoring of quantum walks with weak measurements
Klaus Ziegler, Tim Heine, Sabine Tornow
Measurements can be used to monitor the evolution of quantum systems and can give rise to quantized return statistics. It is known that the mean return time is quantized for strong…
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…
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…
Feedback Connections in Quantum Reservoir Computing with Mid-Circuit Measurements
Jakob Murauer, Rajiv Krishnakumar, Sabine Tornow +1
Existing approaches to quantum reservoir computing can be broadly categorized into restart-based and continuous protocols. Restart-based methods require reinitializing the quantum…
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''…
