Microcomb-driven large-scale fully connected quantum network
Researchers demonstrated a large-scale fully connected quantum network using a microcomb to generate many frequency-correlated photon pairs. This allows any two nodes to directly share entanglement, eliminating the need for a central hub.

Metropolitan-scale quantum networks with direct entanglement links among dozens of nodes could be deployed for fault-tolerant distributed quantum computing within two years.
The microcomb approach consolidates the entanglement source into a single compact device, reducing hardware complexity and making scaling more practical.
