Abstract

Quantum computing is the latest computing concept that can substantially reduce the computational burden of some difficult NP problems. Boolean reversible logic is frequently used as a key component in many quantum algorithms. This study proposes an approach based on a mixed integer programming model for reversible circuit synthesis. The proposed optimization model maps a given reversible function into a multiple-control Toffoli (MCT) circuit with minimum quantum costs. Our model exploits the relationship between MCT gate patterns and the operations on qubit states. We also report our experience in computational experiments on the circuit synthesis of reversible benchmark problems.
