Concentration Scheme for Partially Entangled Atomic States Through Detection of Cavity Decay

Song Wei

Published May 1, 2008• 0 citations
Publisher

Abstract

We propose a scheme for concentrating entanglement of partially entangled states for atoms trapped in the distant cavities. The scheme is based on adiabatic passage and photonic interference. It is robust against a number of practical noises such as the violation of the Lamb–Dicke condition, spontaneous emission and detection inefficiency.

Implementing Entanglement Swapping with Trapped Atoms via Cavity Decay

林秀敏, 喻擘, 周正威 +2 more

With trapped atoms, we propose an experimental scheme to implement entanglement swapping based on adiabatic passage and the detection of cavity decay. This scheme is inherently robust to diverse sources of noise, such as atomic spontaneous emission, or detector inefficiency. The advantages make it realizable with the current experimental technology.

Implementing conditional quantum phase gate via cavity decay

Xiu‐Min Lin, Zheng-Wei Zhou, Chengzhi Wang +2 more

We propose a theoretical scheme to implement the conditional quantum phase gate between distant atoms based on adiabatic passage and the detection of cavity decay. This scheme is inherently robust to diverse sources of noise, for instance, atomic spontaneous emission, output coupling inefficiency and detector inefficiency. Especially, the phase gate can be realized even if the Lamb–Dicke condition is not better satisfied.

Quantum entanglement of distant particles via adiabatic passage

A scheme for quantum entanglement of distant particles via adiabatic passage is proposed.When a Λ-type atom interacts with laser and cavity fields adiabatically,the state of the system evolves in a dark state.As the entanglement of distant atoms or cavities is implemented adiabatically,the proposal is robust to atomic spontaneous emission noise.The biggest success probability is 0.5.
