Reply to comment by Logothetes in Scientists simulate ‘baby’ wormhole without rupturing space and time by Crazy-Sundae-5141

I am a complete ignorant on this subject, but as far as I understand "simulate" refers more to the fact that they used a quantum computer to set up the conditions needed for a what amounts to a "real" wormhole. Quantum computers use entangled particles to process information, and the idea is that entangled particles and wormholes are in fact the same thing.

Quantum computers work by real physics, and so if you set the computer up in a certain specific way you can evoke, detect and measure a real physical phenomenon. In this sense it is not a digital "simulation" per se, as far as I understand. By clumsy analogy, it is more like using a classical computer to measure the speed of an electron by measuring the time it takes for information to be processed.

So in fact, they have created a very real wormhole. Or they have given experimental support to the idea that the math of wormholes fits with the math of entangled particles. They set up entangled particles in a specific way where they turn out to behave exactly the way that "wormhole math" predicts that they should.

This is the correct reading of this result. ADS-CFT correspondence says loosely that the maths of some gravity things matches the maths of some quantum things, when you look at them in the right way. In this experiment they set up the quantum things, looked at them in the right way, and (through the lense of the maths you have to do to look at them the right way) they behaved like the gravity thing. The specific gravity thing they behaved like is a wormhole.

The latter seems about right, or, at least, coincides with my own understanding.

But I comprehend neither the process nor the implied physics well enough to explain it any further, not without the risk of adding, due to my own conceptual errors, more confusion.

There is a 'plain English' [as it were] :) summary available.

This is probably the least nonsensical 'simple' explanation you're likely to get on it.

Cheers!

This is sort of what I've been reading too. Personally I'm pretty excited by this.

So when do we get to turn it into a green portal big enough for, say, a man and his grandson to jump through?

Wait so if they use quantum computers to "simulate" the Big Bang, they'd actually make a big bang but like on a smaller scale?

So they basically did make a wormhole?
