• 2026-01-27
  unconfirmed University of Chicago, Stanford, MIT, Innsbruck, Delft — A Science paper led by David Awschalom argued quantum technology has reached the point the transistor reached in the late 1940s: the physics works and the remaining problems are engineering, manufacturing and modular design.

  It framed 2026 as the start of a scaling era rather than a discovery era.
