This paper examines the problem of ensuring the security of information exchange based on the principles of quantum computing. Within the scope of the study, the stages of user authentication, secret-key generation via quantum states, error detection and correction, and privacy amplification were implemented in software. Based on the obtained secret key, a model was developed in which user data is protected through symmetric encryption while the key itself is transmitted using an asymmetric encryption mechanism. The results of communication sessions are recorded on the basis of blockchain technology, creating the ability to visually analyze the error rate in the system. The proposed approach has practical significance for enhancing information security, detecting eavesdropping attacks, and modeling modern cryptographic systems.
