Quantum Zeno effect and parametric resonance in mesoscopic physics
arXiv:cond-mat/9807317 · doi:10.1103/PhysRevLett.81.5896
Abstract
As a realization of the quantum Zeno effect, we consider electron tunneling between two quantum dots with one of the dots coupled to a quantum point contact detector. The coupling leads to decoherence and to the suppression of tunneling. When the detector is driven with an ac voltage, a parametric resonance occurs which strongly counteracts decoherence. We propose a novel experiment with which it is possible to observe both the quantum Zeno effect and the parametric resonance in electric transport.
