Title
(EN) METHOD FOR SECURELY TRANSMITTING SEQUENCES OF QUANTUM STATES BETWEEN A PLURALITY OF ONLINE PARTICIPANTS OVER A QUANTUM COMMUNICATION CHANNEL
(FR) PROCEDE DE TRANSMISSION SECURISEE DE SEQUENCES D'ETATS QUANTIQUES ENTRE PLUSIEURS PARTICIPANTS EN LIGNE SUR UN CANAL DE COMMUNICATION QUANTIQUE
Abstract
(EN)
The invention relates to a method for securely transmitting a sequence of quantum states between a first participant Ci and a second participant Cj among a plurality of N participants, and to a device implementing said secure transmission method.
(FR)
La présente demande se rapporte à un procédé de transmission sécurisé d'une séquence d'états quantiques entre un premier participant Ci et un second participant Cj parmi une pluralité de N participants et à un dispositif mettant en œuvre ledit procédé de transmission sécurisée.
