Satya P. Gupta,Vaishali M. Patilok in progress—.—edited by David Blair. This chapter is written by Yanbei Chen, and myself. It gives a detailed introduction on how to analyze the quantum noise in advanced GW detectors by using input–output formalism, which is also valid for general optomechanical devices.

In particular, we show that the frequency dependence of double optical springs allows us to create a “negative inertia”, which cancels the positive inertia of the test-mass with the mechanical response significantly enhanced.

This is motivated by the pioneering work of Vyatchanin et?al. [., .], in which such a back-action-evading variational scheme is proposed to detect a force signal with known arrival time.

Achieving the Ground State and Enhancing Optomechanical Entanglement,tomechanical devices, the cavity bandwidth needs to be smaller than the mechanical frequency. This is the so-called resolved-sideband or good-cavity limit. In this chapter, we provide a new but physically equivalent insight into the origin of such a limit: that is information loss due to a finite cavity bandwidth.
