The invention discloses a hierarchical control mixed quantum communication method based on a six-quantum-bit entangled state, and the method comprises the steps: preparing a six-quantum-bit entangled state channel through a supervisor David, and enabling a communicator Alice to transmit a quantum state # imgabs0 # to a communicator Bob through a quantum teleportation technology, a communicator Bob needs to prepare a quantum state # imgabs1 # on one side of a communicator Alice through a remote quantum state preparation technology, and a system state is formed by a single quantum bit unknown state and a quantum channel. And the communicator Alice, the communicator Bob, the supervisor Charlie and the supervisor David obtain corresponding authorization to perform quantum measurement on own quantum bits and send the quantum bits to corresponding objects. According to a measurement result of a communicator Bob, a measurement result of a supervisor Charlie and a measurement result of the communicator Alice, a six-q
