Hybrid quantum algorithm (HQA) was put forward to solve traveling salesman problems.On the basis of quantum computing,displacement decoding was designed which enables the algorithm to overcome the difficulties in route configuration.Evolutionary mode and best tracing and keeping mode,derived from particle swarm optimization algorithm,were adopted,dynamic inertia weight was configured to update quantum angles effectively,and local optimization was taken to carry out lean search.The capability of HQA to solve traveling salesman problems was demonstrated by the results of several examples.
