Wireless Sensor Networks (WSNs) are promoting the spread of the Internet for devices in all areas of 
life, which makes it is a promising technology in the future. In the coming days, as attack technologies become 
more improved, security will have an important role in WSN. Currently, quantum computers pose a significant 
risk to current encryption technologies that work in tandem with intrusion detection systems because it is 
difficult to implement quantum properties on sensors due to the resource limitations. In this paper, quantum 
computing is used to develop a future-proof, robust, lightweight and resource-conscious approach to sensor 
networks. Great emphasis is placed on the concepts of using the BB84 protocol with the AES algorithm in 
WSN security. The results of analysis indicated a high level of security between the data by depending on the 
generation of secure keys, and reached an accuracy rate of about (80-95) % based on using NIST statistical. 
The efficiency of the work increased to 0.704 after using the Quantum Bit Error Rate equation, eventually 
increasing the network performance. This results in the reduction of the overall amount of energy, and the time 
required for performing the key exchange in the encryption and decryption processes decreased.
