First detection probability in quantum resetting via random projective measurements

M Kulkarni, SN Majumdar - Journal of Physics A: Mathematical …, 2023 - iopscience.iop.org
We provide a general framework to compute the probability distribution $ F_ r (t) $ of the first
detection time of a'state of interest'in a closed quantum system subjected to random …

Measurement-induced quantum walks on an IBM quantum computer

S Tornow, K Ziegler - Physical Review Research, 2023 - APS
We study a quantum walk of a single particle that is subject to stroboscopic projective
measurements on a graph with two sites. This two-level system is the minimal model of a …

Continuously monitored quantum systems beyond Lindblad dynamics

G Lami, A Santini, M Collura - New Journal of Physics, 2024 - iopscience.iop.org
The dynamics of a quantum system, undergoing unitary evolution and continuous
monitoring, can be described in term of quantum trajectories. Although the averaged state …

Entanglement of bosonic systems under monitored evolution

Q Liu, K Ziegler - Physical Review A, 2024 - APS
The evolution of noninteracting bosons in the presence of repeated projective
measurements is studied. Following the established approach, this monitored evolution is …

Non-Hermitian description of sharp quantum resetting

R Modak, S Aravinda - arXiv preprint arXiv:2303.03790, 2023 - arxiv.org
We study a non-interacting quantum particle, moving on a one-dimensional lattice, which is
subjected to repetitive measurements. We investigate the consequence when such motion is …

Thermodynamic phases in first detected return times of quantum many-body systems

B Walter, G Perfetto, A Gambassi - arXiv preprint arXiv:2311.05585, 2023 - arxiv.org
We study the probability distribution of the first return time to the initial state of a quantum
many-body system subject to stroboscopic projective measurements. We show that this …

Properties of Fractionally Quantized Recurrence Times for Interacting Spin Models

Q Liu, DA Kessler, E Barkai - arXiv preprint arXiv:2401.09810, 2024 - arxiv.org
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. In …

Repeated measurements and random scattering in quantum walks

K Ziegler - arXiv preprint arXiv:2405.20151, 2024 - arxiv.org
We study the effect of random scattering in quantum walks on a finite graph and compare it
with the effect of repeated measurements. To this end, a constructive approach is employed …

Quantum Systems Subject to Random Projective Measurements

D Das, S Gupta - Facets of Noise: Effects in Classical and Quantum …, 2024 - Springer
In contrast to the previous chapters, we deal in this chapter with quantum systems, and
specifically, with the facet of noise in the sense of uncertainty associated with quantum …
