MULTIPARTY QUANTUM SECRET SHARING OF SECURE DIRECT COMMUNICATION WITH HIGH-DIMENSIONAL QUANTUM SUPERDENSE CODING
The first protocol of multiparty quantum secret sharing of secure direct communication [Phys. Lett. A 342 (2005) 60] is generalized to the high-dimensional case via quantum superdense coding. The generalized protocol has the advantages of higher capacity and better security.
