A New Quantum Dempster Rule of Combination
This work addresses a computational bottleneck in uncertainty reasoning for intelligent information systems, representing an incremental improvement by applying quantum methods to an existing problem.
The authors tackled the exponential computational complexity of the Dempster Rule of Combination as identification framework elements increase by proposing a quantum version using Toffoli gates, which is fully implemented with quantum circuits.
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.
