# Quantum Internet: From Lab Curiosity to National Infrastructure A quantum internet doesn't just send data faster — it sends data in a way that is physically impossible to intercept without detection. That changes everything about security. **Key milestone**: China's Micius satellite demonstrated quantum key distribution (QKD) between ground stations 1,200 km apart. The US DOE has a 10-year roadmap for a quantum network backbone. The core technology is quantum entanglement — two particles linked such that measuring one instantly determines the state of the other, regardless of distance. **2026 reality check**: We have working quantum repeaters in lab conditions. A continental-scale quantum internet is still 10–15 years away. But the foundations are being laid now. → [Full quantum internet explainer →](/node/1362)
