Squeezing of nonlinear spin observables by one axis twisting in the presence of decoherence: An analytical study
In an ensemble of two-level atoms that can be described in terms of a collective spin, entangled states can be used to enhance the sensitivity of interferometric precision measurements. While non-Gaussian spin states can produce larger quantum enhancements than spin-squeezed Gaussian states, their u...
