Designing exceptional-point-based graphs yielding topologically guaranteed quantum search
Quancheng Liu, David A. Kessler, Eli Barkai
Quantum walks underlie an important class of quantum computing algorithms, and represent promising approaches in various simulations and practical applications. Here we design stro…
Driving quantum systems with repeated conditional measurements
Quancheng Liu, Klaus Ziegler, David A. Kessler +1
We investigate the effect of conditional null measurements on a quantum system and find a rich variety of behaviors. Specifically, quantum dynamics with a time independent in a…
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…
The first detection time of a quantum state under random probing
David A. Kessler, Eli Barkai, Klaus Ziegler
We solve for the statistics of the first detection of a quantum system in a particular desired state, when the system is subject to a projective measurement at independent identica…
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…
