VQE (Variational Quantum Eigensolver), a quantum algorithm, can be used to solve combinatorial optimization problems using a quantum computer and a classical computer. A quantum circuit used in VQE is called a PQC (Parameterized Quantum Circuit), and synthesis methods for PQCs that take into account the constraints of the combinatorial optimization problem to be solved have been studied. There is a PQC synthesis method for the Traveling Salesman Problem. In the existing method, only one type of PQC is used to satisfy the constraint conditions, and only one initial value is set for the PQC parameters. Therefore, the PQC proposed in existing method may not be optimal for some problems. In this paper, we propose a method for synthesizing PQC for the Traveling Salesman Problem that takes into account the quantum states generated by PQC. The proposed method synthesizes PQCs by arranging quantum gates in a different way from the existing method. The proposed method reduces the total cost in the Traveling Salesman Problem by 10.43% on average. |
