Abstract
A quantum secure direct communication protocol with cluster states is proposed. Compared with the deterministic secure quantum communication protocol with the cluster state proposed by Yuan and Song (Int. J. Quant. Inform., 2009, 7: 689), this protocol can achieve higher intrinsic efficiency by using two-step transmission. The implementation of this protocol is also discussed.
