Quantum-Secure Communication

Launched in 2016, the Micius satellite, part of the Quantum Experiments at Space Scale (QUESS) project, has surpassed its two-year design life, remaining active in quantum communication experiments as of August 3, 2025. Despite its age, Micius continues to support groundbreaking quantum key distribution (QKD) and entanglement experiments. However, China’s plans for new quantum satellites may shift its role.
