Teleportation of N -qubit W State without Bell-State Measurement via Selective Resonant Interaction in Cavity QED
Wenxue Zhong, Geng Jun, Guangling Cheng, Ai-Xi Chen · Communications in Theoretical Physics · 2010
We present a scheme in which the N-atom W state is teleported by employing the selective interaction of a cavity field with a driven three-level atom in the A configuration and detecting a single atom in one of the ground states. The long-lived W state is teleported from atom A to atom B when the atoms B and A are sent through a cavity successively and atom A is then detected. The advantage is that the present one does not involve the Bell-state measurement and is robust against the atomic spontaneous emission.
