Secure quantum dense coding via tripartite entangled GHZ state in cavity QED
Zheng-Yuan Xue, You-Min Yi, Zhuo-Liang Cao
We investigate economic protocol to securely encoding classical information among three users via entangled GHZ states. We implement the scheme in cavity QED with atomic qubits whe…
Scheme for generating the cluster states via atomic ensembles
Ping Dong, Zheng-Yuan Xue, Ming Yang +1
A scheme for generating the cluster states via atomic ensembles is proposed. The scheme has inherent fault tolerance function and is robust to realistic noise and imperfections. Al…
Quantum dense coding via atomic ensembles without prior distributed entangled state
Zheng-Yuan Xue, Ping Dong, Ming Yang +2
We investigate a scheme for implementing quantum dense coding via atomic ensembles, where prior distribution of the quantum entangled state is not needed. Our scheme also combines…
Generation of cluster states
Ping Dong, Zheng-Yuan Xue, Ming Yang +1
We propose two schemes for the generation of the cluster states. One is based on cavity quantum electrodynamics (QED) techniques. The scheme only requires resonant interactions bet…
Scheme for implementing the Deutsch-Jozsa algorithm via atomic ensembles
Ping Dong, Zheng-Yuan Xue, Ming Yang +1
We propose a physical scheme for implementing the Deutsch-Jozsa algorithm using atomic ensembles and optical devices. The scheme has inherent fault tolerance to the realistic noise…
Concentration for unknown atomic entangled states via cavity decay
Zhuo-Liang Cao, Li-Hua Zhang, Ming Yang
We present a physical scheme for entanglement concentration of unknown atomic entangled states via cavity decay. In the scheme, the atomic state is used as stationary qubit and pho…
