TLDR
In this paper, the authors proposed that the collapse does occur, and it can be explained by the ''environment induced decoherence'' theory, and they showed that the spontaneous emission life time of the atom sets a fundamental limit on the requirement of continuous measurements.Abstract:
The experiment of Etano et al which demonstrated the quantum Zeno effect (QZE) in an optical experiment was explained by Frerichs and Schenzle without invoking the wave function collapse. In this report it is proposed that the collapse does occur, and it can be explained by the `environment induced decoherence' theory. The environment here consists of the completely quantized field vacuum modes. The spontaneous emission life time of the atom sets a fundamental limit on the requirement of `continuous measurements' for QZE. This limit turns out to be related to the time-energy uncertainty relation discussed by Ghirardi et al.read more

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.

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.

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.

Quantum Zeno dynamics and quantum Zeno subspaces
TL;DR: In this paper, the authors focus on the "continuous" version of the quantum Zeno effect and look at several interesting examples in practical terms, towards applications, then propose a novel experiment.
