Metropolitan quantum key distribution network links three regional research hubs

A fiber-based entanglement distribution network connects regional computing nodes, giving independent researchers access to quantum networking hardware.

Quantum networking is transitioning from isolated physics demonstrations to multi-node experimental infrastructure. A fiber-based entanglement distribution testbed was activated connecting three major research nodes across Southeast Asia.

The technical implementation achieves metro-scale quantum key distribution (QKD) over deployed dark fiber links. What distinguishes this network is its open-access policy: a portion of beamtime is allocated to independent community researchers and graduate student projects.

Our quantum computing track is submitting joint research proposals for network layer protocols and entanglement routing experiments.

While metro QKD is an early step toward distributed quantum computing networks, public testbeds accelerate real-world protocol testing and talent development.

Detailed notes and network architecture diagrams are available in our community open research library.

Fascinating analysis. The empirical benchmarks on post-quantum lattice verification align with our lab results.

Will this architecture scale to multi-node clusters without memory bottlenecking?
