GHZ-based Quantum Anonymous Transmission: Difference between revisions

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>.
