A research on service quality decision-making of Chinese communications industry based on quantum game

• We obtain a superior solution than the classic game.
• The optimal service quality decreases in entanglement operator.
• The optimal customer perceived utility increases in entanglement operator.

In recent years, Chinese service industry is developing rapidly. Compared with developed countries, service quality should be the bottleneck for Chinese service industry. On the background of three major telecommunications service providers in China, the functions of customer perceived utilities are established. With the goal of consumer’s perceived utility maximization, the classic Nash equilibrium solution and quantum equilibrium solution are obtained. Then a numerical example is studied and the changing trend of service quality and customer perceived utility is further analyzed by the influence of the entanglement operator. Finally, it is proved that quantum game solution is better than Nash equilibrium solution.
