Quantum Zeno effect in a nonlinear coupler
The dynamics of a spontaneous downconversion process with the idler mode coupled to an auxiliary mode is analysed. Depending on the presence or absence of nonlinear phase mismatch, a Zeno or anti–Zeno effect is found. This behavior is understood by using the dressed modes picture of the device. A possibility to achieve a quasi–phase– matching by careful adjustment of coupling strength is pointe...

متن کاملQuantum 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 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 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...
