Scientists created a wormhole in a quantum computer and observed that information was “teleported”. Studying helps reveal the Theory of Everything

The researchers created a simulation on a quantum computer and observed the formation of a woodworm hole lowercase. The exciting result could not only make interstellar travel possible in the distant future, but also help scientists finally find the Theory of Everything.

Wormholes are bridges connecting points in spacetime, which can be found anywhere in the universe. Through these bridges we could cover the distance separating the points in minutes or seconds.

According to the general theory of relativity of Albert Einstein, wormholes can actually exist. However, the closest we’ve come to finding or producing one is through mathematical calculations and in our imaginations.

Science fiction is a great way to visually explore the idea of ​​a wormhole. An example of this is the film Interstellar (2014), directed by Christopher Nolan. In the story, space travelers use a wormhole located in the vicinity of Saturn to visit the planets around it Gargantua black holein another galaxy.

quantum wormhole




The team started by developing a quantum system using a theoretical model known as Sachdev-Ye-Kitaev (SYK). Wrapping it with another SYK system, they obtained a model capable of preserving gravitational properties.

That model was then reduced to a simplified form with machine learning and then applied to Google’s Sycamore quantum processor. They inserted a qubit (equivalent to a bit in quantum computing) into one of the SYKs and watched the information emerge from the other SYK. It’s as if the data from this qubit were teleported.

Maria Spiropulu, a researcher in the US Department of Energy’s Department of Energy, said the team has found a quantum system that exhibits the key properties of a gravitational wormhole, but is small enough to be implemented in quantum hardware of today”.

For the team, the research is ‘a step towards a larger program of testing the physics of quantum gravity using a quantum computer’.

Why look for a wormhole?

Although wormholes seem to exist only in fiction, scientists are looking to theory and experiments for a way to create them or, at least, to prove that their existence is possible.

One of the main reasons for this is that, like black holes, wormholes could perhaps reveal the secret of quantum gravity. This is because, in both types of “holes”, there must be a building block for both large-scale gravity and quantum gravity.

General Relativity is the best description we have of the large-scale universe (ruled by massive objects), while General Relativity quantum mechanics is the best description of the particle universe. However, both are incompatible, as there is no evidence of a particle responsible for gravity.

Many scientists theorize that inside black holes is something called a singularity, an object smaller than known particles, which contains a huge amount of mass – the numbers tend towards infinity. If something that small has that much mass and exerts that much gravity, that could be where the secret to quantum gravity lies.

quantum teleportation

In 2013, researchers proposed that wormholes could be related to a quantum phenomenon known as “entanglement”. This is the behavior of “twin” particles which, even separated by thousands of light years, share the same information. Change one of these particles and watch the same change occur in the other.

By relating entanglement to wormholes, scientists have come up with the idea of ​​quantum teleportation. This has everything to do with the new wormhole simulation, because the result of the experiment – the transfer of information from one SYK to another – is very similar to particle entanglement.

In other words, information traveled from one quantum system and arose in another via quantum teleportation. If we interpret it in the language of general relativity, this is a journey through a wormhole, albeit a tiny one.

It’s worth remembering, however, that this doesn’t mean we’ll see spacecraft traveling through wormholes. Much work still needs to be done to reproduce the experiment observationally, and not just in a computer simulation.

Also, a wormhole requires a hypothetical type of negative matter with repulsive gravity. The simulation included this, but this matter (known as exotic matter) has yet to be found.
