QUSES is performing a Quantum Key Distribution(QKD) experiment from satellite to ground station for testing of the global quantum secure communication network, and performing a Quantum Entanglement Distribution(QED) and Quantum Teleportation(QT) experiments with the purpose of testing the completeness of quantum mechanics theory at a sufficient spatial scale. The payload of QUSES is com posed of a Quantum Key Transceiver(QKT), a Quantum Entanglement Transmitter(QET), a Quantum Entangled-photon Source(QES), a Quantum Experiment Control Processor(QCP) and a Coherent laser Communication Terminator(CCT). This paper introduces the technical scheme of QUSES, including the requirement analysis, composi tion, technical innovation, on-orbit status and prospect of development for the future.展开更多
