TLDR
Itano et al. as mentioned in this paper analyzed the environment-induced decoherence theory, where the spontaneous emission lifetime of the relevant level emerges as the “decoherence time”.About:

Quantum Zeno dynamics: mathematical and physical aspects
TL;DR: In this article, the authors discuss the physical and mathematical aspects of the quantum quantum Zeno effect and propose alternative strategies to obtain a quantum quantum zeno dynamics and show that they are physically equivalent.
Journal ArticleDOI
Control of decoherence: Analysis and comparison of three different strategies
TL;DR: In this article, the authors analyze and compare three different strategies, all aimed at controlling and eventually halting decoherence, and show that if the frequency of the measurements or pulses is large enough or if the coupling $K$ is sufficiently strong, all these control procedures accelerate decover.
Journal ArticleDOI
Quantum Zeno dynamics
TL;DR: In this paper, the evolution of a quantum system undergoing very frequent measurements takes place in a proper subspace of the total Hilbert space (quantum Zeno effect), and dynamical properties of this evolution are investigated and several examples are considered.

A Conceptual Analysis of Quantum Zeno; Paradox, Measurement, and Experiment
Dipankar Home,M.A.B. Whitaker +1 more
TL;DR: In this paper, it is argued that the quantum Zeno effect is a genuine result of quantum theory and current quantum measurement theory, independent of the projection postulate, and the effect is of very general nature and rests on analogous arguments to those involved in Bell's theories.

Chapter 3 Quantum Zeno and inverse quantum Zeno effects
Paolo Facchi,Saverio Pascazio +1 more
TL;DR: In this article, the quantum Zeno effect is explained in terms of the Schrodinger equation, without making use of projection operators, and a two-level system undergoing Rabi oscillations is considered.

Decoherence and the transition from quantum to classical
TL;DR: In this paper, the authors argue that without quantum physics we could not explain the behavior of solids, the structure and function of DNA, the color of the stars, the action of lasers or the properties of superfluids.
Journal ArticleDOI
The Zeno’s paradox in quantum theory
TL;DR: In this paper, the authors seek a quantum-theoretic expression for the probability that an unstable particle prepared initially in a well defined state ρ will be found to decay sometime during a given interval.

Journal ArticleDOI
Quantum Zeno effect
TL;DR: The quantum Zero effect is the inhibition of transitions between quantum states by frequent measurements of the state by means of pulses of light in an rf transition between two ground-state hyperfine levels.
Journal ArticleDOI
Quantum Zeno effect without collapse of the wave packet
TL;DR: The only experiment in which the Zeno effect has yet been clearly demonstrated, though, allows no conclusion on the necessity or validity of the projection postulate, as shown by calculating the outcome of the experiment on the basis of the standard three-level Bloch equations.
