Thank you for this nice explanation. I skimmed the abstract but didn't really understand it.

All these articles are merely clickbait. I knew there wasn't a real break in RSA before reading the article. It's just some weird subset of usage which allows this. It's nowhere near breaking RSA.

Why are we even contemplating quantum computers breaking encryption when they can't even factorize a 3-digit prime number? I'm wondering if I'll even see quantum computers breaking RSA in my lifetime.
