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. | This [https://arxiv.org/abs/quant-ph/0409201 example protocol] implements the task of [[anonymous transmission]] in a multiple node quantum network.

* In [[GHZ State based Quantum Anonymous Transmission#References|[1] ]] a protocol using another multipartite state, the W state, was introduced. The reference discusses noise robustness of both GHZ-based and W-based protocols and compares the performance of both protocols. | * In [[GHZ State based Quantum Anonymous Transmission#References|[1] ]] a protocol using another multipartite state, the W state, was introduced.
