چکیده
|
On one hand a twolevel atom is utilized as a qubit in quantum information technology and on the other hand the light in quantum optics is usually in the squeezed state. these reasons motivated us to explore the dynamic of a twolevel atom which is driven by a field in the squeezed state. to this goal, the atom operators and the heisenberglangevin equation have been employed. the master equation which reveals the dynamic of the atom has been derived using some features of the squeezed state and doing some algebra. finally, the dynamic of the twolevel atom which is driven by squeezed state field has been simulated by the derived master equation. also, the effect of atom parameters on the dynamic has been investigated.

Abstract
|
On one hand a twolevel atom is utilized as a qubit in quantum information technology and on the other hand the light in quantum optics is usually in the squeezed state. These reasons motivated us to explore the dynamic of a twolevel atom which is driven by a field in the squeezed state. To this goal, the atom operators and the HeisenbergLangevin equation have been employed. The master equation which reveals the dynamic of the atom has been derived using some features of the squeezed state and doing some algebra. Finally, the dynamic of the twolevel atom which is driven by squeezed state field has been simulated by the derived master equation. Also, the effect of atom parameters on the dynamic has been investigated.
