Abstract:  Combining the theories of quantum entanglement, the quantum entanglement genetic algorithm is proposed. The quantum entanglement W state of multiparticle is used to study the entanglement encoding of quantum chromosome. The concrete forms of the quantum update operator, quantum mutation operator, and quantum crossover operator are given. The procedure of quantum entanglement genetic algorithm is also given. Finally, the quantum entanglement genetic algorithm is applied to the designs of microstrip couplers. The results show that the quantum entanglement genetic algorithm has a good optimized speed and the optimization results are very good, too.
