  • Proof-of-principle experimental demonstration of side-channel-secure quantum key distribution over 200 km (2026) · npj Quantum Information · doi

    The gap is the lack of experimental demonstration of SCS-QKD over longer distances with high secure key rates. The gap is due to imperfect vacuum preparation and finite-key constraints under coherent attacks. The gap is also due to the need for stable system operation to accumulate sufficient quantum signals.
