Uncertainty relation between detection probability and energy fluctuations

Felix Thiel, Itay Mualem, David Kessler +1

A classical random walker starting on a node of a finite graph will always reach any other node since the search is ergodic, namely it is fully exploring space, hence the arrival p…

Non-Hermitian and Zeno limit of quantum systems under rapid measurements

Felix Thiel, David A. Kessler

We investigate in depth the relation between the first detection time of an isolated quantum system that is repeatedly perturbed by strong local measurements with a large fixed fre…

Quantization of the mean decay time for non-Hermitian quantum systems

Felix Thiel, David A. Kessler, Eli Barkai

We show that the mean time, which a quantum particle needs to escape from a system to the environment, is quantized and independent from most dynamical details of the system. In pa…

Quantum total detection probability from repeated measurements II. Exploiting symmetry

Felix Thiel, Itay Mualem, David A. Kessler +1

A quantum walker on a graph, prepared in the state , e.g. initially localized at node , is repeatedly probed, with fixed frequency , to test…

Dark states of quantum search cause imperfect detection

Felix Thiel, Itay Mualem, Dror Meidan +2

We consider a quantum walk where a detector repeatedly probes the system with fixed rate until the walker is detected. This is a quantum version of the first-passage problem.…

Uncertainty and symmetry bounds for the quantum total detection probability

Felix Thiel, Itay Mualem, David A. Kessler +1

We investigate a generic discrete quantum system prepared in state , under repeated detection attempts aimed to find the particle in state , for exa…
