recommendations! Published in 2018 at "International Journal of Theoretical Physics"

DOI: 10.1007/s10773-018-3865-5

Abstract: A new three-party quantum key agreement protocol based on seven-qubit states is proposed. In this protocol, each participant adopts different encryption methods to transmit a secret key of the same length. Subsequently, the participants utilize… read more here.
