They didn't even showed that. They only showed that these quantum systems can't be simulated efficiently using a classical computer, using a specific algorithm, the QMC algorithm.
Oh snap, I didn't even notice that bit. That makes this quote so much worse:
> In a paper published in the journal Science Advances, Zohar Ringel and Dmitry Kovrizhi show that constructing a computer simulation of a particular quantum phenomenon that occurs in metals is impossible - not just practically, but in principle.
Maybe Yudkowsky was right about this "sneer club" all along.
This is the best tl;dr I could make, original
reduced by 77%. (I’m a bot) ***** > A team of theoretical physicists
from Oxford University in the UK has shown that life and reality cannot
be merely simulations generated by a massive extraterrestrial
computer.

Quantum Monte Carlo methods use random sampling to analyse many-body
quantum problems where the equations involved cannot be solved
directly.
of course somebody who's convinced we're living in a simulation is also engaging in highly intellectual speculation about whether the las vegas shooter was a muslim
They proved no such thing. They only showed that certain quantum systems can’t be simulated efficiently using a classical computer.
