  Dempster rule of combination (DRC) is widely used for uncertainty reasoning
in intelligent information system, which is generalized to complex domain
recently. However, as the increase of identification framework elements, the
computational complexity of Dempster Rule of Combination increases
exponentially. To address this issue, we propose a novel quantum Dempster rule
of combination (QDRC) by means of Toffoli gate. The QDRC combination process is
completely implemented using quantum circuits.
