Implementing quantum information splitting using a five-partite cluster state in cavity QED

Abstract

We propose an explicit scheme for splitting up quantum information into parts using five-atom cluster states in cavity quantum electrodynamics (QED). It is found that the quantum information splitting of an arbitrary two-atomic state can be realized by using the five-atom cluster state. During the process, the cavity fields are excited only virtually. The scheme is insensitive to cavity decay. Therefore, the scheme can be experimentally realized using a range of current cavity QED techniques. The schemes considered here are also secure against certain eavesdropping attacks.

Quantum-information splitting using multipartite cluster states

Sreraman Muralidharan, Prasanta Kumar Panigrahi

We provide various schemes for the splitting up of quantum information into parts using four- and five-partite cluster states. Explicit protocols for the quantum information splitting (QIS) of single- and two-qubit states are illustrated. It is found that the four-partite cluster state can be used for QIS of an entangled state and the five-partite cluster state can be used for QIS of an arbitrary two-qubit state. The schemes considered here are also secure against certain eavesdropping attacks.

SPLITTING QUANTUM INFORMATION WITH FIVE-ATOM ENTANGLED STATE IN CAVITY QED

Xiao-Jie Yi, Jianmin Wang, Guo-Qiang Huang

A realizable scheme is proposed for implementing quantum information splitting with five-atom entangled state in cavity QED, where we explicitly illustrate the procedure and analyze the security against the eavesdropping. The scheme does not involve Bell-state measurement and is insensitive to the cavity and the thermal field.

Possible Realization of Cluster States and Quantum Information Transfer in Cavity QED via Raman Transition

Zhiming Zhan, Weibin Li

We present a scheme to generate cluster states with many atoms in cavity QED via Raman transition. In this scheme, no transfer of quantum information between the atoms and cavities is required, the cavity fields are only virtually excited and thus the cavity decay is suppressed during the generation of cluster states. The atoms are always populated in the two ground states. Therefore, the scheme is insensitive to the atomic spontaneous emission and cavity decay. We also show how to transfer quantum information from one atom to another.

Quantum Information Splitting Based on Current Cavity QED Techniques

Huai‐Zhi Wu, Zhen‐Biao Yang, Wan-Jun Su +2 more

We propose two schemes for quantum information splitting via W-class state. The first scheme is based on the interaction of single atom with single-mode field, while the second scheme is based on the simultaneous interaction of two atoms with single-mode cavity. For the first scheme, the difficulty of two atoms required to be simultaneously sent through one cavity is avoid. For the second scheme, it is immune to thermal field. Both schemes are experimentally feasible based on current cavity QED techniques.
