The presented GHZ-based quantum anounymous transmission protocol is based on the work of [[GHZ State based Quantum Anonymous Transmission#Refrences|[6] ]]. The goal of the protocol is to transmit a quantum state <math>|\psi \rangle</math> from the sender <math>S</math> to the receiver <math>R</math>, while keeping the identities of <math>S</math> and <math>R</math> anonymous. We assume that there is exactly one receiver which is determined before the start of the protocol. The protocol consists of the following steps: | The presented GHZ-based quantum anounymous transmission protocol is based on the work of [[GHZ State based Quantum Anonymous Transmission#Refrences|[6]]].
