Generation of Entangled Coherent States for Two Separate Cavities

Li-Hua Lin

We propose a scheme for the generation of entangled coherent states for two separate cavities connected by an optical fiber. In the scheme, an atom is trapped in the first cavity and driven by a strong classical field. Under the condition that the cavity-fiber coupling is much larger than the atom-cavity coupling, the two cavity modes evolve from a vacuum state to entangled coherent states correlated with the atomic states. During the evolution, the fiber mode is not excited and the fiber loss does not affect the fidelity of the produced state.

Nonclassical properties of the excited double-mode SU(2) coherent state

Wan Guang-ren

The excited double-mode SU(2) coherent state is introduced and its nonclassical properties are investigated with numeric method. The results exhibit that when the photons are added to the fields of the double mode SU(2) coherent state, the two field modes can preserve anti-correlation character. The violation of Cauchy-Schwartz inequality, the sub-Poissonian photon statistics properties and the anti-bunching effect of the fields are all enhanced.

Continuous-variable quantum teleportation of entanglement

Tyler J. Johnson, Stephen D. Bartlett, Barry C. Sanders

Entangled coherent states can be used to determine the entanglement fidelity for a device that is designed to teleport coherent states. This entanglement fidelity is universal in that the calculation is independent of the use of entangled coherent states and applies generally to the teleportation of entanglement using coherent states. The average fidelity is shown to be a poor indicator of the capability of teleporting entanglement; i.e., very high average fidelity for the quantum teleportation apparatus can still result in low entanglement fidelity for one-mode of the two-mode entangled coherent states.
