Summary
Can integrated sources serve many quantum-communication clients?
Uses one optical microcomb chip as seed and phase reference for 20 transmitter chips.
Demonstrates sequential pairwise twin-field QKD over wavelength channels and spooled fibre.

Commentary
This is a proof-of-principle communication network, not universal quantum computation or simultaneous service of every pair.
Source coherence, phase locking and fabrication reproducibility become system-level constraints.
