Quantum Secure Direct Communication by Swapping Entanglements of 3×3-Dimensional Bell States
Abstract
By swapping entanglements of 3×3-dimensional Bell states, we propose a quantum secure direct communication scheme, whose advantage is to own the high source capacity. In addition, another light point is that only one set of measuring basis is needed in this scheme.
