Controlled teleportation of an unknown two-particle entangled state through the raman interaction
Xiong Kuang · Journal of Atomic and Molecular Physics · 2008
A four-particle entangled state of atoms and cavity is prepared through the Raman interaction of Λ-type three-level atom with coherent cavity-field.The four-particle entangled state is used as the quantum channels,and one of the particles in the channel is used as the controlled qubit.We can realize the controlled teleportation of an unknown two-particle entangled state.Based on present cavity QED techniques,We give a brief discussion on the experimental feasibility.
