Nonclassical characteristic functions for highly sensitive measurements

Quantum Physics 2009-11-13 v2

Abstract

Characteristic functions are shown to be useful for highly sensitive measurements. Redistributions of motional Fock states of a trapped atom can be directly monitored via the most fragile nonclassical part of the characteristic function. The method can also be used for decoherence measurements in optical quantum-information systems.
