ABSTRACT

Although some classical algorithms have been applied to solve the satisfiability problem, more effective methods are still explored because existing algorithms are constrained by inadequate computing capability of traditional computers. The parallelism of quantum computation makes quantum algorithms with promising potential to improve the computing ability, but existing quantum algorithms still require too large number of qubits to solve a simple problem effectively. In this paper, an optimized data structure was structured to solve Boolean satisfiability problem by utilizing Grover's algorithm, and then the corresponding formula was proposed to balance variables in consideration of complexity. With reasonable simplification, quantum circuits were built to decrease the number of qubits required in Grover's algorithm. The result of verification experiment further demonstrated that the proposed approach is simple, reliable and of a certain practical value.
