Generalized minimum-uncertainty squeezed states
Evgeny V Shchukin, Th. Kiesel, W. Vogel · Physical Review A · 2009
Generalized squeezed states, related to a broad class of observables, are analyzed. Methods for characterizing the properties of such states are developed, which are based on numerical solutions of ordinary differential equations. As typical examples we deal with nonlinear generalizations of quadrature squeezed states and deformed nonlinear squeezed states, which may be useful for optimized measurements at a reduced level of quantum noise. The realization of such states is studied for the quantized center-of-mass motion of a trapped ion.
