Scientists Build 'Baby' Wormhole

An anonymous reader quotes a report from Reuters: Scientists have long pursued a deeper understanding of wormholes and now appear to be making progress. Researchers announced on Wednesday that they forged two miniscule simulated black holes -- those extraordinarily dense celestial objects with gravity so powerful that not even light can escape -- in a quantum computer and transmitted a message between them through what amounted to a tunnel in space-time. It was a "baby wormhole," according to Caltech physicist Maria Spiropulu, a co-author of the research published in the journal Nature. But scientists are a long way from being able to send people or other living beings through such a portal, she said.

"Experimentally, for me, I will tell you that it's very, very far away. People come to me and they ask me, 'Can you put your dog in the wormhole?' So, no," Spiropulu told reporters during a video briefing. "...That's a huge leap." [...] Spiropulu said the researchers found a quantum system that exhibits key properties of a gravitational wormhole but was small enough to implement on existing quantum hardware. The researchers said no rupture of space and time was created in physical space in the experiment, though a traversable wormhole appeared to have emerged based on quantum information teleported using quantum codes on the quantum processor. "There's a difference between something being possible in principle and possible in reality," added physicist and study co-author Joseph Lykken of Fermilab, America's particle physics and accelerator laboratory. "So don't hold your breath about sending your dog through the wormhole. But you have to start somewhere. And I think to me it's just exciting that we're able to get our hands on this at all."

"It looks like a duck, it walks like a duck, it quacks like a duck. So that's what we can say at this point -- that we have something that in terms of the properties we look at, it looks like a wormhole," Lykken said.
