Airborne Quantum Links vs. Space-Based Backbones: Deconstructing NASA’s Tactical QKD Test and the Micius Generational Divide
Viral narratives framing NASA's airborne quantum key distribution test as a leap past China's Micius satellite mistake tactical low-altitude links for intercontinental space infrastructure. Transmitting single photons through turbulent tropospheric boundary layers differs fundamentally from leveraging vacuum-dominated 500 km orbital channels.
NASA首试机载量子通信：战术低空链路与墨子号的代际鸿沟
外网热传 NASA 首次打通空地量子链路并赶超中国，实测项目仅系低空战术无人机防干扰测试。机载链路需在全对流层湍流中对抗气溶胶衰减与机体震颤，而墨子号卫星凭借 98% 外太空真空信道与亚微弧度精密对准构建起洲际广域骨干，两者分属战术终端与天基战略基座。
