"Scientists may have...that ability could...early experiments suggest...if verified, it could..."

I have become jaded with publications that hedge like this. In my experience most of these discoveries never pan out, they just disappear. And not being in the field myself, I don't know how to judge.

Does anyone in quantum computing have a read on how big a deal this is (or isn't)?

The manuscript has been out since October 2025, and back then it didn't make so much noise. Looks like solid work, but more muted in tone than this press release. https://arxiv.org/abs/2510.08110

The limiting factor for quantum computers is keeping them cold. Is this triple superconductor high temperature too? If not, it's not going to change things much.
