This [https:// | This [https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.122.240501 example protocol] implements the task of [[Anonymous Transmission]] in a multi-node quantum network. The protocol uses an untrusted <math>n</math>-partite GHZ state to enable two nodes, Sender and Receiver, to establish a link which they use to transmit a quantum message. In addition to adversarial nodes, the source of the GHZ state may be controlled by an adversary. To address this, the protocol includes verification of the GHZ state. It incorporates a reduced fidelity GHZ state used for anonymous transmission, resulting in a notion of anonymity for imperfect scenarios called <math>\epsilon</math>-anonymity. | ||
