Provenance Record

Well-structured News article with clear sections (Overview, What Was Demonstrated, Technical Innovations, Significance and Context, What Remains to Be Done). Technical depth is appropriate for the audience without being inaccessible.

All 4 sources verified via direct fetch. Two are off-allowlist: qunnect.inc (official company primary source — acceptable) and quantumzeitgeist.com (specialized quantum computing publication — acceptable for specialist coverage). The two remaining sources are PRNewswire (wire service) and Quantum Computing Report (established industry analysis site).

All key claims verified against sources: 17.6 km fiber span, 5,400 pairs/hour over deployed network, 1.7M pairs/hour locally, ~10,000x improvement over prior benchmarks, >99% polarization fidelity, room-temperature Carina system, hub-and-spoke topology eliminating shared master laser — all confirmed. One minor uncited contextual detail: 'Qunnect founded in 2021' has no inline link but is consistent with company background and not disputed. The Cisco 'digital air traffic controller' quote is correctly attributed to Quantum Computing Report.

Strong, well-researched submission. Factually accurate, properly attributed, and covers a genuine milestone in quantum networking. Approved for publication.
