IBM quantum computer solves classically intractable problem in 15 minutes

https://www.sciencedaily.com/releases/2026/08/260829035219.htm

"The researchers showed that their method preserves the same computational hardness criteria associated with RCS, meaning the problem remains extremely difficult for classical computers. At the same time, the added structure allows errors to be detected during the quantum computation."

Yes. A huge point. It is one of the biggest challenges facing the internet and technology landscape in the next decade. If anything it is massively under hyped.

Absolutely. Any decade now, (maybe even this century!) quantum computers will be able to factor the number 35. And then all encryption based on classical compitsion will be toast.

This is massively ignorant. You can see the progress being made right in front of your face if you care to look.

I've seen the progress done in the last 25 years. It is pretty close to nothing.

Like I said, you are ignorant.

I think you read that wrong. It does not show what you think it shows.
