摘      要：We present a quantum hyperdense coding protocol with hyperentanglement in polarization and spatial-mode degrees of freedom of photons first and then give the details for a quantum secure direct communication(QSDC)protocol based on this quantum hyperdense coding *** QSDC protocol has the advantage of having a higher capacity than the quantum communication protocols with a qubit *** with the QSDC protocol based on superdense coding with𝑑-dimensional systems,this QSDC protocol is more feasible as the preparation of a high-dimension quantum system is more difficult than that of a two-level quantum system at present.
