It's not just a random tweet. He's had these ideas since 2013 at least. So here for more details: https://davidgerard.co.uk/blockchain/buterins-quantum-quest/

  > competent observers would likely consider even that on the high side for a mathematical impossibility If the statement made by Vitalik "There's no proof that efficient classical simulation of QC is impossible" is indeed the case, then it's the linked blogpost that has discredited itself mathematically by treating this as "breaking mathematics" or a "mathematical impossibility". More like groundbreaking surprise, but there's a big difference between "unlikely" and "proven to be impossible" mathematically speaking.

    The element of controversy isn't whether efficient quantum simulation is possible, but the idea that by running such a simulation one would be able to break cryptography, as if they were using an actual quantum computer. This is a talk where he makes this claim https://youtu.be/DkUpZkeqhF4?t=3372 https://youtu.be/DkUpZkeqhF4?t=3372 If this isn't crackpottery of the highest degree I don't what is.

      A talk from 8 years ago, when he was 18 years old? I mean, even having a semi-half-baked opinion on quantum cryptography at 18 is pretty damn impressive. Just because everything is forever on the internet does not mean that opinions are forever.
