Sensitivity of a cavityless optomechanical system
arXiv:quant-ph/0312166 · doi:10.1103/PhysRevA.70.045801
Abstract
We study the possibility of revealing a weak coherent force by using a pendular mirror as a probe, and coupling this to a radiation field, which acts as the meter, in a cavityless configuration. We determine the sensitivity of such a scheme and show that the use of an entangled meter state greatly improves the ultimate detection limit. We also compare this scheme with that involving an optical cavity.
