Measurement-induced spin squeezing in a cavity
arXiv:cond-mat/0304127 · doi:10.1103/PhysRevA.68.043820
Abstract
Spin squeezing of an ensemble of N atoms in a high-Q cavity is shown to be enhanced by continuous measurement of photons in the cavity. A degree of spin squeezing proportional to N^{-1/3} is attained as a quasi-steady state over a broad set of initial states of the atoms and photons.
