论文摘要
我们提出了一种在使用振荡器的测量过程中克服量子反作用的新方法。光学振荡器用作测量另一个开放振荡器的参数。合成光学振荡器，以使光学恢复力对抗量子反作用现象引起的任何扰动。结果，证明连续测量中的量子反作用在低频率状态下被抑制，即比开放振荡器的谐振频率小得多。当仪表扮演测量参数的作用以及抑制量子反作用的作用时，我们称其为量子反作用仪表。作为这种方法的应用，描述了量子反作用的合成无效光振荡器，以抑制线性和非线性验光力学中的辐射压力噪声。
We propose a new method to overcome quantum back-action in a measurement process using oscillators. An optical oscillator is used as a meter to measure the parameters of another open oscillator. The optical oscillator is synthesized such that the optical restoring force counters any perturbations induced by the quantum back-action phenomena. As a result, it is shown that the quantum back-action in continuous measurement is suppressed in the low frequency regime i.e., for frequencies much smaller than the resonance frequency of the open oscillator. As the meter plays the role of measuring parameters as well as suppressing the quantum back-action, we call it as quantum back-action nullifying meter. As an application of this method, synthesis of quantum back-action nullifying optical oscillator for suppressing radiation pressure force noise in linear and non-linear optomechanics is described.
