Departamento de Qu´imica-F´isica, UPV-EHU, Apartado 644, 48080 Bilbao, SpainRepeated measurements of a quantum particle to check its presence in a region of space wasproposed long ago (G. R. Allcock, Ann. Phys. 53, 286 (1969)) as a natural way to determine thedistribution of times of arrival at the orthogonal subspace, but the method was discarded because ofthe quantum Zeno effect: in the limit of very frequent measurements the wave function is reflectedand remains in the original subspace.

Detector Models for the Quantum Time of Arrival
Quantum particles are characterized, for a given preparation, by a fundamental stochasticity of their observable features, such as positions, momenta, energies, or times, e.g., times of arrival at a
Quantum time of arrival distribution in a simple lattice model
Imagine an experiment where a quantum particle inside a box is released at some time in some initial state. A detector is placed at a fixed location inside the box and its clicking signifies arrival
Time-of-arrival probabilities for general particle detectors
We develop a general framework for the construction of probabilities for the time of arrival in quantum systems. The time of arrival is identified with the time instant when a transition in the
Quantum arrival time formula from decoherent histories
We use the decoherent histories approach to quantum mechanics to compute the probability for a wave packet to cross the origin during a given time interval. We define class operators (sums of strings
A review of the decoherent histories approach to the arrival time problem in quantum theory
We review recent progress in understanding the arrival time problem in quantum mechanics, from the point of view of the decoherent histories approach to quantum theory. We begin by discussing the
Suppression of quantum-mechanical reflection by environmental decoherence
In quantum mechanics an incoming particle wave packet with sufficient energy will undergo both transmission and reflection when encountering a barrier of lower energy, but in classical mechanics
Reflection of a particle from a quantum measurement
We present a generalization of continuous position measurements that accounts for a spatially inhomogeneous measurement strength. This describes many real measurement scenarios, in which the rate at
Generalized relation between pulsed and continuous measurements in the quantum Zeno effect
A relation is found between pulsed measurements of the excited-state probability of a two-level atom illuminated by a driving laser and a continuous measurement by a second laser coupling the excited
Decoherent histories analysis of minisuperspace quantum cosmology
Recent results on the decoherent histories quantization of simple cosmological models (minisuperspace models) are described. The most important issue is the construction, from the wave function, of a
Amplitudes for spacetime regions and the quantum Zeno effect: pitfalls of standard path integral constructions
Path integrals appear to offer natural and intuitively appealing methods for defining quantum-mechanical amplitudes for questions involving spacetime regions. For example, the amplitude for entering


Chapter 3 Quantum Zeno and inverse quantum Zeno effects
This chapter discusses the quantum Zeno and inverse quantum Zeno effects. The quantum Zeno effect is a consequence of the new dynamical features introduced by a series of measurement processes. In
The time of arrival in quantum mechanics II. The individual measurement
Abstract It is first shown that the time at which a moving classical particle reaches a fixed space point can be measured with arbitrarily high precision by the use of a suitably conceived apparatus.
Time-of-arrival probabilities and quantum measurements
In this paper we study the construction of probability densities for time of arrival in quantum mechanics. Our treatment is based upon the facts that (i) time appears in quantum theory as an external
Control of decoherence: Analysis and comparison of three different strategies (22 pages)
We analyze and compare three different strategies, all aimed at controlling and eventually halting decoherence. The first strategy hinges upon the quantum Zeno effect, the second makes use of
Quantum Zeno effect by general measurements
It was predicted that frequently repeated measurements on an unstable quantum state may alter the decay rate of the state. This is called the quantum Zeno effect (QZE) or the anti-Zeno effect (AZE),
Continuous and pulsed quantum zeno effect.
Continuous and pulsed quantum Zeno effects were observed using a 87Rb Bose-Einstein condensate and it is observed that the continuous measurements exhibit the same suppression in the transition rate as the pulsed measurements when gammadeltat=3.60(0.43), in agreement with the predicted value of 4.5%.
A Conceptual Analysis of Quantum Zeno; Paradox, Measurement, and Experiment
Abstract Arguments on controversial points concerning quantum measurement theory and the quantum Zeno effect are presented. In particular it is argued that (1) the quantum Zeno effect is a genuine

Abstract This paper contains further discussion of the phenomena and problems of interpretation which arise when a nonrelativistic quantum particle falls upon an apparatus designed to measure the
Quantum arrival times and operator normalization
A recent approach to arrival times used the fluorescence of an atom entering a laser illuminated region, and the resulting arrival-time distribution was close to the axiomatic distribution of
