Abstract

This work proposes a dense coding using four-particle cluster states. Based on the dense coding, an efficient deterministic secure quantum communication (DSQC) is devised. The quantum bit efficiency of the proposed DSQC is better than the other DSQCs also using four-particle cluster states.
