A quantum computer simulates a wormhole for the first time

The possibility of taking a shortcut and going from one point in the universe to another very far away, if it exists at all (eg Theory of relativity in Albert Einstein), it is tested via technology.

Maria Spiropolou of the California Institute of Technology and fellow researchers used Google’s quantum computer Sycamore to simulate “worm hole hologram ”- in the language of astronomy,“ wormhole ”(warm in English) will be a tunnel Through space-time that would allow travel to infinityby having black holes at each end.

Scientists simulated a type of wormhole through which a message could pass, and examined what that journey would be like.

For this simulation, the “message” was a signal containing a qubit (quantum bit) in a superposition of 1’s and 0’s. It entered one side of the artificial wormhole and exited the other. Success! Like teleportation.

If we were dealing with a real wormhole (no one has yet been able to prove its existence; it’s just a theoretical possibility), then such a trip would be completely different, mediated by gravity. But the holographic model uses quantum effects as a substitute for gravity. This greatly simplifies the simulation.

“The signal fades away, it turns to mush, it becomes a mess, and then it gets put together again and looks authentic on the other side,” says Speropoulou. “Even in this small system, we can maintain the wormhole and observe exactly what we’d expect.” This is due to quantum entanglement between black holes, allowing information that falls at one end of the wormhole to be preserved at the other.

The greatest questions

Simulations like these can help understand how these two concepts can be integrated into a quantum theory of gravity — perhaps the most difficult and important problem in physics right now. Because both quantum mechanics, which governs very small relativity, and general relativity, which describes gravity and very large relativity, succeed in their own fields…but don’t say hello on the street. They just don’t fit…

This is where holography comes into play. It allows physicists to create a system that is less complex but equivalent to the original, in the same way that a 3D hologram can show 3D details.

The creation of these scientists preserves the mystery about the existence of wormholes. But he does hint at how it could lead to amazing interstellar travel in the future, if that is even possible. 🇧🇷 Not only in the field of theory.
