In view of the problems of high power,low computing power and low transmission and communication efficiency of quantum modules,the key technologies of low-power development of quantum modules are studied.The Gradient Ascent Pulse Engineering (GRAPE) algorithm is used to optimize the quantum gate,and the optimal pulse sequence is found through iterative calculation,which can improve the computing power and reduce the power consumption of the quantum module.Quantum Entanglement Feedback Control (QEFC) is used to optimize the quantum transmission communication,which can enhance the efficiency of communication and reduce the power consumption by monitoring and feeding back the quantum system.The experiment results show that the CZ accuracy of GRAPE algorithm can reach 96%.The average fidelity of the optimized QEFC model can reach 0.97 under amplitude damping interference and 0.92 under depolarization channel,which is much higher than before optimization.In the space plasma environment,the bit error rate after optimization is only 0.009,which is much lower than that before optimization.It can be seen that the computing power and transmission efficiency of the optimized quantum module can be greatly improved,thus reducing the power consumption.
