The GHZ-based quantum anonymous transmission protocol implements the task of [[anonymous transmission]] in a <math>n</math>-node quantum network. The protocol uses <math>n</math>-partite [[GHZ state]] to enable two nodes, sender <math>S</math> and receiver <math>R</math>, to establish a link which they use to transmit a quantum message. Importantly, the quantum message is transmitted in a way that the identity of <math>S</math> is unknown to every other node, and the identity of <math>R</math> is known only to <math>S</math>.  
This [https://arxiv.org/abs/quant-ph/0409201 example protocol] implements the task of [[anonymous transmission]] in a multiple node quantum network. The protocol uses <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. Importantly, the quantum message is transmitted in a way that the identity of sender is unknown to every other node, and the identity of receiver is known only to sender.
