摘要：

Recently, Yeo and Cha introduced a genuine four-qubit entangled state vertical bar chi > which can implement perfect teleportation of an arbitrary two-qubit state [Y. Yeo, W.K. Chua, Phys. Rev. Lett. 96 (2006) 060502]. It has been shown that the state vertical bar chi > is inequivalent to the well-known Greenberger-Horne-Zeilinger state, IN state, and linear cluster state, in terms of stochastic local operations and classical communication [C.F. Wu, Y. Yeo, L.C. Kwek. C,H. Oh, Phys. Rev. A 75 (2007) 032332]. This "new" class of state has many interesting entanglement properties and possible applications in quantum-information processing and fundamental tests of quantum mechanics. Here, we propose a simple scheme to generate the state vertical bar chi > in cavity quantum electrodynamics. Our idea may be helpful for in-depth study on such a class of state and its practical applications. (C) 2008 Elsevier B.V. All rights reserved.
