摘要：
In this paper, we show that current two different quantum channels of two three-qubit GHZ states and the six-qubit entangled state can be used for quantum teleportation of an arbitrary two-qubit state deterministically. Moreover, we propose two distinct protocols for quantum teleportation of an arbitrary two-qubit state within a three-qubit, by using a single-qubit measurement under the basis and also using a two-qubit projective measurement under the basis {|+⟩,|-⟩}\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\{|+\rangle ,|-\rangle \}$$\end{document}, so as to get 16 kinds of possible measured results with equal probability of 1/4. Furthermore, the deterministic quantum teleportation of an arbitrary two-qubit states can be realized in a cavity quantum electrodynamics systems. This is unique, in that a cluster state has a maximal persistence when compared with a entangled state and it is also more robust against decoherence. Furthermore, the schemes are secure against internal and external attacks.
