No they didn't.

(Posting this before I read the article. I will edit this comment after I have read it.)

Edit: Welp, second sentence:

>While the results don’t reveal anything new about lithium-ion batteries, they demonstrate how more powerful quantum computers could be used to accurately simulate complex chemical reactions in the future.

It's easy for a throwaway like me to hate. On the other hand, I have a cursory interest in quantum computing (I like listening to podcasts, occasionally read blogs like Shtetl-Optimized, and try to stay up to date somewhat?) and it's cool to see different applications in the wild that are novel. Even if but a modicum of progress.

A rule-of-thumb for any basically any quantum news is that, if it were true as the title suggests, you'd be hearing about it everywhere. It would be leading in every publication.
