The switching behavior they see could just be an electron hopping on and off a quantum dot, perhaps one formed incidentally by part of the wirelike region, Legg says. “This is exactly what you could get from a quantum dot.”

Anyone want to give a layman-ish explanation of why aluminum versus lead makes such a huge difference?

Leading with this dubious claim is fine comedy. Microsoft can barely build a useful conventional computer that runs its own platform and associated products. The Surface Book 3's being used at my job all launch Teams, Excel and Outlook like they're perpetually struggling to get out of bed. The Surface Pros have display issues minutes out of the box. This foolish Dash to Quantum will result in a lot of disappointment as unreliable rushed-to-market hardware is tauted by companies like Microsoft that are historically fond of doing just that.

And no, I don't think quantum computing is all hype. There is definitely meat on the bone, even if it only returns us to the somewhat annoying days of time sharing that most HN readers are probably too young to remember. But these idiots are fueling the hype train for the sake of quick-buck valuation, puffing for an audience that is increasingly tired of over-promising and under-delivering to the point where we will finally have an actual quantum computer and nobody will give a shit, especially after this whole AI circus has continued to prove itself an expensive pagent full of mummers and gimmicks.
