Reply to comment by TheRealOneTwo in Breakthrough wormhole simulation may unite quantum physics and general relativity by Gari_305

It wasn't even actually simulated. This entire article is clickbait for the stupid.

> All they did was perform elaborate SYK calculations on a classical computer, together with simulations of noise on the Google quantum computer, trying to find a possible calculation on the quantum computer that would have signal, not just noise. Once such an N=7 SYK calculation was identified, they used a 9 qubit quantum computer and the noisy result matched the simulation result from the classical computer, exactly as expected.

I mean, what kind of simulation is there other than math on a computer

One that actually models something. A more correct title would be "quantum computer confirms solution to a 10 year old equation previously solved by classical computers, that implies wormholes may exist"

The journalism on this is ridiculously exaggerated, it if you care about fundamental physics it is interesting that they have created a model that is quantum but has the key properties of an ER bridge; it is basically a toy that they can play with to get ideas on how to tackle the real problem. This sort of thing is done a lot in physics and math, it’s not worth all the publicity but if you’re into the search it is interesting…
