Spin-squeezed states for metrology
Alice Sinatra
Abstract
Spin-squeezing is a well-established “quantum technology,” where well-designed correlations in an ensemble of two-level systems reduce the statistical uncertainty of spectroscopic experiments. This paper reviews some important advances in the field, with emphasis on the author's contributions concerning, in particular, the fundamental limits imposed by decoherence. Building on the material presented in the first part, new ideas and some promising developments are outlined in the last section.
