 * '''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:''' 1.The verifier sends angles to each party that corresponds to measurement basis, using classical authenticated channels
+* '''Verification phase:''' The verifier choses and sends angles to each party that corresponds to measurement basis, using classical authenticated channels. Each party, including the verifier, measures its qubits in the basis indicated by the received angle. It then sends its outcome to the verifier who checks the parity of the outcomes and broadcast if the shared state was a GHZ state.
