Control of Squeezed Phonon and Spin States
In this paper we analyze the quantum control of squeezed states of harmonic oscillators as well as spin squeezing and its relationship to quadrature squeezed states of other bosonic fields. Squeezing provides a method for reducing noise below the quantum limit and provides an example of the control of under-actuated control systems in the stochastic and quantum context. We consider also the int...
متن کاملSqueezed light from spin-squeezed atoms.
We propose to transfer quantum correlations from atoms to light by Raman scattering of a strong laser pulse on a spin-squeezed atomic sample. We prove that the emission is restricted to a single field mode which perfectly inherits the quantum correlations of the atomic system.
متن کاملControl of Squeezed States
In this paper we consider the classical and quantum control of squeezed states of harmonic oscillators. This provides a method for reducing noise below the quantum limit and provides an example of the control of under-actuated systems in the stochastic and quantum context. We consider also the interaction of a squeezed quantum oscillator with an external heat bath.
متن کاملThermalization of Squeezed States
We first of all propose a simple definition of a thermal squeezed state. Previous definitions of thermal coherent states and squeezed states[1, 2] have used the thermofield approach of Takahashi and Umezawa[3]. An early paper by Vourdas[4] discusses the superposition of squeezed states with thermal photons; a more recent paper[5] considers only the case of thermal coherent states. An early stud...
متن کاملGeneralized Squeezed States from Generalized Coherent States
Both the coherent states and also the squeezed states of the harmonic oscillator have long been understood from the three classical points of view: the 1) displacement operator, 2) annihilation(or ladder-) operator, and minimum-uncertainty methods. For general systems, there is the same understanding except for ladder-operator and displacement-operator squeezed states. After reviewing the known...
