量子系统中的噪声抵消效应

Noise cancellation effect in quantum systems

Paolo Solinas, Nino Zanghi

摘要:

我们考虑简单量子系统在控制参数随机涨落影响下的时间演化。我们表明,当参数波动足够快,有一个消除噪声的效果。我们建议,这样的效果可以通过实验观察到一个简单的实验与捕获的离子。作为我们分析的副产品,我们提供了对原子光学中绝热布居转移技术的随机扰动的鲁棒性的解释。

英文摘要:

We consider the time evolution of simple quantum systems under the influence of random fluctuations of the control parameters. We show that when the parameters fluctuate sufficiently fast, there is a cancellation effect of the noise. We propose that such an effect could be experimentally observed by performing a simple experiment with trapped ions. As a byproduct of our analysis, we provide an explanation of the robustness against random perturbations of adiabatic population transfer techniques in atom optics.
