Decoherence and the Quantum Zeno Effect
Anu Venugopalan, R. Ghosh
Abstract
The measurements in the optical test of quantum Zeno effect [Itano et al. Phys. Rev. A41 (1990) 2295) are analyzed using the environment-induced decoherence theory, where the spontaneous emission lifetime of the relevant level emerges as the 'decoherence time'. The implication of this finite decoherence time in setting a fundamental limit on the realizability of the condition of continuous measurements is investigated in detail.
