The University of Adelaide is reporting the ability to fire one billion electrons per second using quantum mechanics; repeatedly. This is a major step to “reliable, continuous, and consistent” electron flow using quantum mechanics, a ‘must have’ for quantum computing. Clicking image takes you to schematic’s abstract.
