Modern communication systems increasingly operate in environments where some participating users cannot be trusted. This motivates the study of Byzantine communication models, in which legitimate users may behave adversarially. In this work, we investigate a compelling scenario: a multiple-access channel with multiple transmitters and one receiver, where one transmitter deviates from the protocol and acts dishonestly. To address this challenge, we introduce the Byzantine multiple-access classical-quantum channel and derive the communication region of rate for this adversarial setting.
