Quantum Anti–Zeno Effect
The interplay between quantum dynamics and quantum measuments continues to attract attention of physicists since the birth of quantum physics [1]. One of the classic examples of such an interplay is the, so called, quantum Zeno effect [2]. It consists in modifying the quantum evolution by the repeated measurments. The essence of the quantum Zeno effect is that repeated interrogation if the syst...
متن کاملUnderstanding the quantum Zeno effect
The quantum Zeno effect consists in the hindrance of the evolution of a quantum system that is very frequently monitored and found to be in its initial state at every single measurement. On the basis of the correct formula for the survival probability, i.e. the probability of finding the system in its initial state at every single measurement, we critically analyze a recent proposal and experim...
متن کاملInverse Quantum Zeno Effect in Quantum Oscillations
It is shown that inverse quantum Zeno effect (IZE) may exist in a three-level system with Rabi oscillations between discrete atomic states. The experiment to observe IZE in such a system is proposed. PACS numbers: 03.65.Bz
متن کاملQuantum Zeno effect: Quantum shuffling and Markovianity
The behavior displayed by a quantum system when it is perturbed by a series of von Neumann measurements along time is analyzed. Because of the similarity between this general process with giving a deck of playing cards a shuffle, here it is referred to as quantum shuffling, showing that the quantum Zeno and anti-Zeno effects emerge naturally as two time limits. Within this framework, a connecti...
متن کاملQuantum Zeno and Anti-Zeno Effect without Rotating Wave Approximation
The effect of the anti-rotating terms on the short-time evolution and the quantum Zeno (QZE) and anti-Zeno (AQZE) effects is studied for a two-level system coupled to a bosonic environment. A unitary transformation and perturbation theory are used to obtain the electron self-energy, energy shift and the enhanced QZE or the AQZE, simultaneously. The calculated Zeno time depends on the atomic tra...
