Generation of Squeezed States: Rydberg Atoms in a High Q Cavity
Squeezed states  of the quantum EM field are characterised by having the fluctuations in one quadrature component of the electric field smaller than that for a coherent state. This is a non classical feature and the theory of the generation of squeezed states has been studied in a wide variety of non linear atom-field processes. Such states have possible applications in spectroscopy, communications, gravitational wave detection and so on. Squeezed states have recently been observed experimentally using the process of non degenerate four-wave mixing in an optical cavity . References to the many papers on squeezed states may be found in the review by Walls  and in the recent paper by Reid and Walls .
