Abstract

Realizing the teleportation of a quantum state, specially the teleportation of a many-qubit quantum state, is of great importance in quantum information. A scheme of teleporting a two-qubit unknown atomic state was proposed. In this scheme, a three-particle entangled state is used as quantum channel to teleport a two-qubit atomic state.

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.

A Scheme for Teleportation of an Unknown Multi-atom Entangled State via Raman Interaction

Ma Song-She

A scheme is proposed to teleportation of an unknown multi-atom entangled state, considering the entangled states of two or more particles play an important role in both demonstrating quantum nonlocality and quantum information processing. The scheme is based on the degenerate Raman interaction of a Λ-type three-level atom with a single-mode field. First let n atoms cross a coherent cavity field in succession to prepare a quantum channel. Then the sender lets the other n atoms which carry the unknown state cross the cavity in succession and makes a joint measurement by detecting the cavity field and the atoms separately. When ｜α｜1, the cavity field can be detected with the measurement method of detecting orthogonal states. Finally the receiver reconstructs the initial state according to the outcome of the joint measurement transmitted through a classical channel. The advantage of the scheme is that it uses an entangled state of a coherent state with n atoms as a quantum channel, which makes the scheme simple and easy. The scheme is expected to be useful in demonstrating quantum nonlocality and information processing.
