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…

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…

Scheme for sharing classical information via tripartite entangled states
Zheng-Yuan Xue, You-Min Yi, Zhuo-Liang Cao
We investigate schemes for quantum secret sharing and quantum dense coding via tripartite entangled states. We present a scheme for sharing classical information via entanglement s…
