The dynamic properties of the two-level entangled atom in an optical field

YU Ben-li

Published Jan 1, 2003• 0 citations

Abstract

The interaction of an optical field and one of the entangled atoms is analyzed in detail in this paper. Furthermore, the dynamic properties of the two-level entangled atom are manifested. The properties of the action are dependent on the initial state of the atom. After detecting the atom out of the field, we can obtain the state of the other atom moving in the field. It is shown that the state of the atom out of the field influences the dynamic properties of the atom in the field.

The Level-split of the Two-level Entangled Atom in an Optical Field

Zhuo‐Liang Cao, Huang Ting, Guo Guang-Can +1 more

The behavior of a two-level entangled atom in an optical field with circular polarization is studied in this paper. The interaction of an optical field and one of the entangled atoms is analyzed in detail. A general solution of the SchrAo¨Gdinger equation about the motion of the entangled atom is obtained. The properties of the action are dependent on the initial state of the atom. By detecting the entangled atom out of the field, we can obtain the state of the other atom moving in the field. It is shown that the state of the atom out of the field will influence the energies of the split-levels of the atom in the field.

The entanglement dynamics of two entangled atoms in the dissipative cavity

Chunlei Jiang, Mao-Fa Fang, Wu Zhen-Zhen +1 more

In this paper, we investigate the entanglement dynamics of two entangled two-level atoms interacting with a single-mode field in a dissipative cavity. The results show that the evolution properties of the entanglement degree of two entangled atoms depend on the initial atomic entanglement degree and form, the average photon number of the cavity field, and the cavity leakage rate. When the atoms are initially in a particular entangled state, the degree of entanglement can be amplified and not influenced by the dissipation of the cavity field.

Quantum properties of light of two identical two-level entangled atoms interacting with coherent state

Song Jun, Zhuo‐Liang Cao

In this article, the quantum properties of light in the system of the two identical two-level entangled atoms interacting with the coherent optical field are studied by means of time evolution operator and numerical calculations. The results indict that the time evolution of the squeezing and coherence properties of the light depends on the degree of entanglement of the initial two identical two-level entangled atoms and the intensity of the coherent optical field.

Quantum properties of light field of two identical two-level entangled atoms interacting with radiation fields in binomial states

Song Jun, Zhuo‐Liang Cao

In this article, the quantum properties of light field of the two identical two-level entangled atoms interacting with the binomial optical field were studied by means of time evolution operator and numerical calculations. The results show that the time evolution of the squeezing and coherence properties of the light field depends on the entanglement degree of the initial two identical two-level entangled atoms and the parameters of the binomial optical field. The optical field fluctuation can be completely squeezed via choosing appropriate parameters.
