Measurement-induced spin squeezing in a cavity
Hiroki Saito, Masahito Ueda
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.
