Almost a century ago, Albert Einstein realized that the equations of general relativity could produce wormholes. But it would take a number of theoretical leaps and a “crazy” team of experimentalists to build one on Google's quantum computer. Read the full article at Quanta Magazine:The idea seems to be that if entanglement and wormholes are the same thing, and quantum computers use entanglement to do super-Turing computations, then there should be some wormholes hiding inside a quantum computer. Seems like a joke to me, but I did not read the details.
See Peter Woit for details. At least one physicist calls it a publicity stunt. The quantum computer researchers have burned a lot of money, and need something to show for it.
Update: A comment:
Even if the headline isn’t strictly accurate (a topic for another time, although I think you’re splitting hairs here), what’s the harm? It’s a cool-sounding result which gets people interested in theoretical physics, science more generally. As long as science journalists are driving interest and engagement, I think they’re doing a good job. If you want to discuss bad science journalism, surely a better use of your time would be all the anti-science fake news coming from the populist right in the U.S.I suspect that this view is common. Over-hyped phony stories generate interest and funding. If you want to be a good Leftist, you should not call out Leftist lies. Instead you should devote that energy to attacking right-wingers!
Update: Scott Aaronson admits that the wormhole story is a big hoax, promoted by physicists who should know better. He also discusses a new paper saying that quantum supremacy is impossible. He says it is no surprise to experts in the field who have known since 2016 that scaling up quantum computers will not work. He is still a believer:
So, though it’s been under sustained attack from multiple directions these past few years, I’d say that the flag of quantum supremacy yet waves. The Extended Church-Turing Thesis is still on thin ice.That is, he says that he has not been proved wrong yet. Okay, but he hasn't been proved right either.
