Universal dynamical control of quantum mechanical decay: modulation of the coupling to the continuum

AG Kofman, G Kurizki - Physical review letters, 2001 - APS
We derive and investigate an expression for the dynamically modified decay of states
coupled to an arbitrary continuum. This expression is universally valid for weak temporal …

Quantum computing using single photons and the Zeno effect

JD Franson, BC Jacobs, TB Pittman - Physical Review A—Atomic, Molecular …, 2004 - APS
We show that the quantum Zeno effect can be used to suppress the failure events that would
otherwise occur in a linear optics approach to quantum computing. From a practical …

Non-Gaussian correlations imprinted by local dephasing in fermionic wires

PE Dolgirev, J Marino, D Sels, E Demler - Physical Review B, 2020 - APS
We study the behavior of an extended fermionic wire coupled to a local stochastic field.
Since the quantum jump operator is Hermitian and quadratic in fermionic operators, it …

Readout-induced suppression and enhancement of superconducting qubit lifetimes

T Thorbeck, Z Xiao, A Kamal, LCG Govia - Physical Review Letters, 2024 - APS
It has long been known that the lifetimes of superconducting qubits suffer during readout,
increasing readout errors. We show that this degradation is due to the anti-Zeno effect, as …

Universal dynamical decoherence control of noisy single-and multi-qubit systems

G Gordon, N Erez, G Kurizki - … of Physics B: atomic, molecular and …, 2007 - iopscience.iop.org
In this paper, we develop, step by step, the framework for universal dynamical control of two-
level systems (TLS) or qubits experiencing amplitude or phase noise (AN or PN) due to …

Anti-Zeno quantum advantage in fast-driven heat machines

V Mukherjee, AG Kofman, G Kurizki - Communications Physics, 2020 - nature.com
Developing quantum machines which can outperform their classical counterparts, thereby
achieving quantum supremacy or quantum advantage, is a major aim of the current research …

Quantum zeno and anti-zeno probes of noise correlations in photon polarization

S Virzì, A Avella, F Piacentini, M Gramegna, T Opatrný… - Physical review …, 2022 - APS
We experimentally demonstrate, for the first time, noise diagnostics by repeated quantum
measurements, establishing the ability of a single photon subjected to random polarization …

Quantum Zeno effect with partial measurement and noisy dynamics

P Kumar, A Romito, K Snizhko - Physical Review Research, 2020 - APS
We study the quantum Zeno effect (QZE) induced by continuous partial measurement in the
presence of short-correlated noise in the system Hamiltonian. We study the survival …

Quantum anti-Zeno effect without wave function reduction

Q Ai, D Xu, S Yi, AG Kofman, CP Sun, F Nori - Scientific reports, 2013 - nature.com
We study the measurement-induced enhancement of the spontaneous decay for a two-level
subsystem, where measurements are treated as couplings between the excited state and an …

Quantum evolution in the stroboscopic limit of repeated measurements

IA Luchnikov, SN Filippov - Physical Review A, 2017 - APS
We consider a quantum system dynamics caused by successive selective and nonselective
measurements of the probe coupled to the system. For the finite measurement rate τ− 1 and …
