Natalie WolchoverPhysicists have used Google's quantum computer to send a signal through a wormhole, a shortcut in space-time first theorized by Einstein and Rosen in 1935. The landmark experiment was published today in Nature. Lots to say about it. Here's my very deep dive: https://www.quantamagazine.org/physicists-create-a-wormhole-using-a-quantum-computer-20221130/
John Francis@nattyover wat?! hmmm...starts reading...
jdw@nattyover A bit dated but a good summary of #LeonardSusskind presenting his explanation of #ER=EPR
Leonard Susskind | "ER = EPR" or "What's Behind the Horizons of Black Holes?" - 1 of 2
Heidi Li Feldman@nattyover Your article is terrific. I am not all expert in the relevant physics but with my passing familiarity, I was able to follow your discussion, thanks to its exceptional clarity.
Jakub Konecki@nattyover could you please clarify for me if we're really talking about a wormhole in space-time or if this is 'only' entanglement of qubits?
Kaladin 🧑🦽💨From what I read it's relative proof that when qubits are entangled, it *must be through* a wormhole in spacetime. That is to say there is a transport for entanglement.
@windrunner @nattyover oh! I haven't heard that entanglement = ERP wormhole before. This is very exciting.
One Meat Ball ✔️@nattyover Somewhat clickbaitish. The "wormhole" they refer to is a computer simulation, unrelated to the wormholes of our own physical realm.
Justin Derrick@Onemeatball @nattyover Given the relative infancy of quantum computing, it was an interesting first try - I'm skeptical that the result (and what was inferred from it) will hold true, but I found the whole entanglement/wormhole thing interesting, as best as I could understand it.

Love this phrase from the initial caption: "though it’s not clear in what sense the wormhole can be said to exist."
And this related one is a close runner up: "but how to conceptualize this kind of duality remains mysterious."

Natalie I’m a big fan but the description here is crap. What happened to the word “simulation”?

Chuck Darwin"Seeing the completely expected match between results from a 9 bit noisy quantum computer and the results of the simulation of this on a classical computer caused Maria Spiropulu to say that “I was shaken” and “It was nuts. It was nuts”, while Joe Lykken felt that the moment was on a par with discovery of the Higgs particle."
