Yeah, your instincts are correct. I have shared this paper in my company's quantum slack channel (wasn't aware we had one) after I shared it in the watercooler channel. We will see how this goes...

I have asked people to debunk it or at least give some defense of the research field. I'm not a cryptographer but this article wasn't over my head and makes a pretty strong case for suspicion of the demos. The tech industry has a long track record of faking stuff. Vaporware is a real thing.

My take on this is the same as bitcoin. I wanna see steel-man arguments, not straw-man ones. Poke holes in it. Is the logic flawed? Its easy to throw around technical info and dazzle people with your bs. We have seen it over and over again in the crypto space. Seemingly smart people being fooled over and over again.
