What the current evidence supports

Human editorial judgment · 2026-08-20

Track; not yet

Why
Peer-reviewed in Science with concrete, falsifiable numbers and a real mechanism, but the artifact is a sub-millimetre research crystal: no wafer-scale film, no device stack beyond transport, no stated timeline, and no replication outside the originating group - nothing to adopt or procure yet
Next
Re-check in two quarters for (a) an independent lab reproducing >99% ABC phase purity via step-guided Cu-Ni-on-alumina growth and (b) continuous ABC area scaling past ~1 mm2 or a demonstrated stitched device-grade sheet
