Nevertheless the very right-skewing curves they show have been published before.. maybe the breakthrough is in enabling a class of experiments that are easier to realize (since their model is described as being &quot;minimal&quot;) a more familiar analogy would be to the implementation of adiabatic logic approaching the Landauer limit. Not nearly simple enough to scale all the way to your pocket, but enough for nsf/DoD(?) to continue funding it.</p><p><a href="https://hackerpaper.kaipfister.de/p/2501.11317/">Paper and discussion history</a>.
