Teleportation of N -qubit W State without Bell-State Measurement via Selective Resonant Interaction in Cavity QED

Abstract

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.

Teleportation of a Superposition of Three Orthogonal States of an Atom without Bell-State Measurement

Zhong Zhi-Rong

A scheme to teleport a superposition of three orthogonal states of an atom without Bell-state measurement in cavity QED is proposed. The scheme based on the resonant interaction of two Λ-type three-level atoms with a bimodal cavity. The detection of atom a collapses atom b to the initial state of atom a with cavity mode left in two-mode vacuum state. The probability of success and the fidelity of this scheme are 0.112 and 0.999, respectively.

Teleportation of a three-particle W state without the Bell-state measurement

Rong‐Can Yang

We propose a scheme for teleportation of an unknown three-atom W state without the Bell-state measurement. Firstly, we prepare an unknown three-atom W state by the resonant interaction between the atoms and the cavity. Then a quantum channel is prepared by sending two atoms through a single-mode cavity field, and driving them by a strong classical field at the same time. During the interaction between the atoms and the cavity, the states of these atoms are evolved. After the interaction, we prepare the EPR states, which form the quantum channel. Finally, we implement the teleportation of the unknown three-atom W state using the way of preparing the quantum channel. During the teleportation, the effects of thermal field and cavity decay are all eliminated. The success probability is 1.0.

A scheme for approximate conditional teleportation of entangled two-mode cavity state without Bell state measurement

Zhong Zhi-Rong

An alternative scheme to approximately conditionally teleport entangled two-mode cavity state without Bell state measurement in cavity QED is proposed. The scheme is based on the resonant interaction of a ladder-type three-level atom with two bimodal cavities. The entangled cavity state is reconstructed with only one atom interacting with the two cavities successively.

We present a simple scheme for teleporting an unknown atomic state using an atomic Bell state in cavity QED system.Our scheme can use single-atom detection instead of Bell-state measurement with the help of an auxiliary atom,and its successful probability can reach 1.In addition,the scheme is insensitive to the cavity decay and the thermal field.
