Scientists Manage to Simulate a ‘Baby’ Wormhole in a Quantum Computer

The experiment will allow scientists to study the possibility of the existence of quantum gravity , a hypothetical theory of physics .


Scientists have managed to simulate a wormholewith a quantum computer, trying to give rise to the theory of quantum gravity .

These wormholes, which would function as a bridge between two regions of space-time, have not been verified, but they are compatible with the Theory of Relativity. Now, this simulation opens the doors to its study in a deeper way.

A breakthrough

The researchers, who published their results in Nature , say they succeeded in creating two tiny black holes and transmitting a message between them.

The experiment was carried out on the Google Sycamore processor and represents a further step towards the possibility of studying quantum gravity , a hypothetical theory that unites quantum physics with gravity, both of which are inherently incompatible.

“We have found a quantum system that exhibits the key properties of a gravitational wormhole, yet is small enough to be implemented on current quantum hardware,” explained Maria Spiropulu, lead author of the study.

we are still far

The authors of the study themselves made it clear that scientists are still a long way from being able to send people or other living beings through such a portal.

“Experimentally, for me, I’ll tell you it’s a long, long way away. People come to me and ask, ‘Can you put your dog in the wormhole?’ So, no,” Spiropulu told reporters during a video briefing. “That’s a big leap.”

“There is a difference between something being possible in principle and actually possible,” added physicist and study co-author Joseph Lykken of Fermilab, the US particle physics and acceleration laboratory. “So don’t hold your breath about sending your dog through the wormhole. But you have to start somewhere. And I think it’s exciting to me that we can get our hands on this.”
