Erratum: Arbitrated quantum signature of classical messages against collective amplitude damping noise (Opt. Commun. 283 (2010) 3198–3201)

Abstract We discover an error in the quantum circuit in Fig. 2 in the original paper [ Y.G. Yang, Q.Y. Wen. Opt. Commun. 283 (2010) 3198–3201 ]. Corrected results are obtained and presented in this paper.
