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

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 …
