GHZ-based Quantum Anonymous Transmission: Difference between revisions

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 the sender is unknown to every other node, and the identity of the receiver is known only to the sender.
