Light as a quantum back-action nullifying meter

We propose a new method to overcome quantum back-action in measurement process using oscillators. An optical oscillator is used as meter measure the parameters of another open oscillator. The synthesized such that restoring force counters any perturbations induced by phenomena. As result, it shown continuous suppressed low frequency regime i.e., for frequencies much smaller than resonance plays role measuring well suppressing back-action, we call nullifying meter. an application this method, synthesis radiation pressure noise linear and non-linear optomechanics described.
