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…
