The first investigation by Gardiner of the interaction of a squeezed vacuum with a two-level atom showed that the two quadratures of the atomic polarization can decay at vastly different rates [.]. The decay of a particular atomic polarization quadrature may be greatly inhibit

Engineering Collective and Squeezed Field Interactions,ept of the collective behavior of atoms discussed in Chap. . was based on the assumption that distances between the atoms are smaller or comparable to the resonant wavelength. At such small distances, the atoms can behave collectively and we have seen that the collective effects are manifested in th

The reason for this was that squeezed light is an example of a nonclassical state of the electromagnetic field with quantum fluctuations in one of the two field quadrature components

These pioneering applications of squeezed light have faced many practical problems and it has taken 27 years for their first experimental verification [., .].
