Backaction noise produced via cavity-aided nondemolition measurement of an atomic clock state
arXiv:0807.4762 · doi:10.1103/PhysRevA.78.051803
Abstract
We use a quantum nondemolition measurement to probe the collective pseudospin of an atomic ensemble in a high-finesse optical cavity. We analyze the backaction antisqueezing produced by the measurement process to show that our protocol could create conditional spin squeezing in the atomic ensemble.
