Abstract

Considering three two-level atoms initially in the GHZ state,two atoms of the three atoms are put into initially empty cavity and made resonant interaction.The two-atom entanglement properties inside cavities are investigated by means of the quantum theory and numerical calculations.Through comparing the results if a rotation operation and direct selective measurement is performed or not,the influences of a rotation operation and state-selective measurement of the atom outside the cavity on the two-atom entanglement evolution inside cavities are discussed.The results obtained using the numerical method show that the two-atom entanglement properties inside cavities is controlled by manipulating the atom outside the cavity,and it can be strengthened by seleting suitable rotation angle.

Influence of selective atomic measurement on the entanglement properties of a two-atom outside cavity

LU Dao-ming

Considering three two-level atoms initially in the W or Greenberger—Home—Zeilinger (GHZ) state, one of the three atoms is put into an initially coherent light cavity and made to resonantly interact with the cavity. The two-atom entanglement evolution outside the cavity is investigated. The influences of state-selective measurement of the atom inside the cavity and strength of the light field on the two-atom entanglement evolution outside the cavity are discussed. The results obtained from the numerical method show that the two-atom entanglement outside the cavity is strengthened through state-selective measurement of the atom inside the cavity. In addition, the strength of the light field also influences the two-atom entanglement properties.

Considering that three two-level atoms are initially in the GHZ single state and two of the atoms are simultaneously put into a cavity initially in the coherent state, we investigate the dipole squeezing properties of the two atoms inside the cavity under the condition of resonant interaction. It is shown that dipole squeezing properties of the two atoms inside the cavity are strongly affected by rotation manipulating of the atom outside the cavity.

Considering three two-level atoms initially in the GHZ state, then one atom of them is put into an initially empty cavity and made resonant interaction. It is shown that the emission properties of the atom inside the cavity can be affected only when both of the atoms outside the cavity have been manipulated. This conclusion can also be generalized to n two-level atoms.
