Abstract
In this chapter, we describe an experimental setup, e.g., the 5-mg suspended mirror, geometry of the optical cavity, vibration isolation system, laser source, calibration method, detection and vacuum system. Figure 5.1 shows the displacement noise due to the quantum back-action that sets our goal of sensitivity in displacement measurement. At the resonant frequency of the pendulum (130 Hz is supposed), the displacement noise is approximately \(1\times 10^{-12}\) m/\(\sqrt{\mathrm{{Hz}}}\). Every component has to be specially designed to achieve the sensitivity needed to detect the quantum back-action. Especially, we explain how to measure the back-action using the optically coupled oscillator in detail because it is the special case where the feed-back force for length control is transferred to the 5-mg suspended mirror via the optical spring effect. The relevant publication is Phys. Rev. A 92, 033825 (2015) [1].
