The abstract We propose a quantum digital signature scheme to enhance security and ensure non-repudiation within quantum communications. Our scheme is designed to integrate seamlessly with the key protocols for efficient data transmission in quantum systems including quantum teleportation and superdense coding. By coupling the inherent security features of quantum communication with our scheme, we present an innovative approach that significantly bolsters the reliability and trustworthiness of quantum information exchange, marking a step forward in the quest for invulnerable quantum communication networks.
