NEW FOUR-MODE CHARGE-RELATED ENTANGLED STATE REPRESENTATION

Hong-Yi Fan, Ou-Yang Jing

Published Oct 20, 2003• 3 citations
Publisher

Abstract

We construct a new kind of four-mode charge-related entangled state |q,k;n,m>θϕ in Fock space, which can describe the process of photons, emitted from two energy levels in a optical cavity, being absorbed by another two levels simultanuously. The relation between |q,k;n,m>θϕ and the four-mode entangled state |η,σ,τ>θϕ (H.-Y. Fan et al., Mod. Phys. Lett.B16, 861 (2002)) is pointed out.

New Three-Mode Charge-Related Entangled State Representation

Fan Hong-Yi, Junhua Chen

We construct a new kind of three-mode charge-related entangled state | q , k ; n ⟩ θ in three-mode Fock space, which possesses the completeness relation and orthogonal property. It can describe when photons emitted by two energy levels simultaneously are absorbed by the third energy level. The relation between | q , k ; n ⟩ θ and the tripartite entangled state |η,σ⟩ θ [Chin. Phys. Lett. 18 (2001) 1301] is pointed out.

SQUEEZING ENHANCED THREE-MODE ENTANGLED STATE

Liyun Hu, Hong-Yi Fan

By virtue of the technique of integration within an ordered product of operators (Fan et al., Ann. Phys.321 (2006) 480) we construct a kind of three-mode entangled squeezed state in the Fock space, which exhibits stronger squeezing in one quadrature than that of the usual two-mode squeezed vacuum state.

SOME NEW RELATIONS BETWEEN TARGET STATE AND QUANTUM TELEPORTED STATE GAINED BY VIRTUE OF THE |η> REPRESENTATION

Hong-Yi Fan, Yue Fan

Based on the entangled state representation <η| in two-mode Fock space (Fan and Klauder, Phys. Rev.A49, 704 (1994)), we provide an alternative approach for analyzing quantum teleportation of continuous variables and go a step further by deriving some relations between input (target) states and teleported states. The natural representation of the two-mode squeezing operator in the |η> representation greatly simplifies our calculations.

Scheme for Generating a χ-Type Four-Atom Entangled State in Cavity QED

Lin Xiu

We propose a scheme for generating a χ-type four-atom entangled state in cavity QED. In the present scheme, the atoms interact simultaneously with a highly detuned cavity mode with the assistance of a strong classical field. The scheme is insensitive to the cavity decay and the thermal field, which is of importance from the experimental point of view.
