Abstract:
     This invention discloses a method for direct quantum communication transmission in steps safely utilizing the coherence and non-locality of tangling particles to load the effective information onto the quantum state directly in terms of a coding way agreed on by send/receive parties to transmit the effective information on the quantum channel in steps. Transmission in steps means that at least a set information of tangling particles in a same quantum state is divided into two related particle sequences, the two sides transmit one particle sequence first then the send party codes its own particle sequence and sends it to the receiver to be read out by a joint measurement device.
