Generation of Entangled Bloch States for Two Atomic Samples Trapped in Separated Cavities

Abstract

A scheme is presented for the generation of entangled states for two atomic ensembles trapped in two distant cavities. In the scheme, each atomic sample is initially in a Bloch state and the cavity mode is initially in a coherent state with a small amplitude. The dispersive atom-cavity interaction leads to a photon-number dependent phase shift on the atomic system. The detection of a photon leaking from the cavities makes the two atomic samples collapse to an entangled Bloch state.

Generation of Three-Dimensional Entangled States for Two Atoms Trapped in Different Cavities

Zheng Shi-Biao

We propose a scheme for generating three-dimensional entangled states for two atoms trapped in two separate cavities. The scheme is based on the detection of photons leaking from the cavities after the atom-cavity interaction. The scheme is useful for the test of quantum nonlocality and quantum information processing.

Efficient Scheme for Entangling Two Distant Atoms

LU Dao-ming, Zheng Shi-Biao

A scheme is presented for the generation of entangled states for two atoms trapped in two distant cavities. In the scheme each atom is resonantly coupled with the respective cavity mode and driven by a strong classical field. The detection of a photon decaying from the cavities and passing through a beam-splitter collapses the atoms to an entangled state. The required atom-field interaction time is very short and thus the decoherence effect is suppressed. Our scheme is within the reach of presently available cavity QED techniques.

Entangling Two Atomic Ensembles Trapped in Separated Cavities

Shi‐Biao Zheng, LU Dao-ming

We propose a scheme for the generation of two collections of atoms trapped in distant cavities connected by an optical fiber. The virtual photon exchange leads to the entanglement between these two atomic ensembles. During the operation the atomic system, cavity modes, and fiber are not excited, which is important in view of decoherence.

Scheme for Generating a Two-atom Entangled State via Cavity Decay

Lihua Zhang

The author presents a quantum scheme for generation of a two-atomic entangled state via cavity decay.When two single-photon detectors only detect one photon,which leaks out from the two cavities simultaneously,two distant atoms will be created into a pair of maximally entangled state with a certain probability.

Deterministic generation of entangled coherent states for two atomic samples

LU Dao-ming, Zheng Shi-Biao

This paper proposes an efficient scheme for deterministic generation of entangled coherent states for two atomic samples. In the scheme two collections of atoms are trapped in an optical cavity and driven by a classical field. Under certain conditions the two atomic samples evolve from an coherent state to an entangled coherent state. During the interaction the cavity mode is always in the vacuum state and the atoms have no probability of being populated in the excited state. Thus, the scheme is insensitive to both the cavity decay and atomic spontaneous emission.
