In order to solve the existing problems of limited communication capacity, low communication rate, small communication coverage, and low communication quality, the present invention proposes a quantum communication system, including a quantum gateway system, a quantum information carrier, a transfer channel system and a physical channel system. Quantum information carriers include bosons such as photons and Fermi-type superpartners such as photons, fermions such as electrons, and particles such as electron superpartners. Transfer channel systems include, but are not limited to, Banach spaces and Hilbert spaces. Physical channel systems include, but are not limited to, fiber optic transmission systems. The application of the entanglement state properties between qubits in the quantum communication system can effectively solve the problems of limited communication capacity, low communication rate, small communication coverage, low communication quality, and high communication cost in the existing communication system, and at the same time reduce the non-trivial communication in the process of information transmission. Linear effect, once the improvement of communication quality has been applied in practice, the research and development of capacity expansion and speed-up will have a brighter future than the current optical fiber communication.
