Remote Three-Party Quantum State Sharing Based on Three-Atom Entangled States Assisted by Cavity QED and Flying Qubits

Tie-Jun Wang, Fu‐Guo Deng

We present a remote three-party quantum state sharing (QSTS) scheme with three-atom Greenberger—Horne—Zeilinger (GHZ) states assisted by cavity QED and flying qubits. It exploits some photons to act as the flying qubits for setting up the quantum channel securely with three-atom systems in a GHZ state, which maybe make this remote QSTS scheme more practical than some other schemes based on atom systems only or ion-trap systems as photons interact with their environments weakly. The coherence of the stationary atom qubits in cavities provides the convenience for the parties in QSTS to check eavesdropping, different from entangled photon systems. Moreover, the present scheme works in a collective-noise condition and it may be more practical than others in applications in future.

Preparation of Atom Entangled States Based on Cavity QED

Xin Jun-li

For the sake of making this kind of useful quantum information resource of quantum entanglement.Here we propose a new prepare process on the foundation of the cavity quantum electrodynamics technique project of the resonance interaction,put forward a kind of making process that atom entangled state.Made to prepare two typical quantum entangled states in cavity QED: GHZ and W states of atoms,which belong to inequivalent classes of entangled states.GHZ state is maximally entangled state,while W states are non-maximally entangled states.They hold many interesting applications in quantum information processing and high-precision measurements.Therefore it is expected to be implemented with the current cavity QED experimental technology.
