* '''Sharing phase:''' The source creates and shares an n-qubits quantum state to all the parties using a state generation resource and quantum channels. | * '''Sharing phase:''' The source creates and shares an n-qubits quantum state to all the parties using a state generation resource and quantum channels. | ||
* '''Verification phase:''' The verifier | * '''Verification phase:''' 1.The verifier sends angles to each party that corresponds to measurement basis, using classical authenticated channels | ||
2. Each party, including the verifier, measures its qubits in the basis indicated by the received angle. | |||
3. It then sends its outcome to the verifier. | |||
4. The verifier checks the parity of the outcomes and broadcast if the shared state was a GHZ state. | |||
