What the current evidence supports

Human editorial judgment · 2026-08-20

Track; not yet

Why
This is a first-of-kind laboratory physics result, peer-reviewed and genuinely surprising (entanglement without a laser, Bell-violating), but it is a bench demonstration with no vendor, no product, a ~4.7x un-normalised pair-rate deficit against laser-pumped SPDC (which the authors argue closes once bandwidth is accounted for), a 2.49-sigma Bell violation, and an explicit author statement that field deployability is future work. There is nothing adoptable, so the correct posture is to watch the brightness and stability curve rather than to pilot.
Next
Re-probe on the next arXiv revision, an Optica follow-up, or the first announced brightness/field-deployability figure from the uOttawa-MPL team or the independent Xiamen group; no procurement or integration action in this cycle.
