Quantum locking of mirrors in interferometers

arXiv:gr-qc/0212081 · doi:10.1103/PhysRevLett.90.083601

Abstract

We show that quantum noise in very sensitive interferometric measurements such as gravitational-waves detectors can be drastically modified by quantum feedback. We present a new scheme based on active control to lock the motion of a mirror to a reference mirror at the quantum level. This simple technique allows to reduce quantum effects of radiation pressure and to greatly enhance the sensitivity of the detection.
