The first hands-on project to create a wormhole in the lab which serves as a bridge between space and the interior of the universe was presented by the University of Bristol.

Through an innovative computer scheme, published in the magazine Quantum Science and Technologythat takes advantage of the basic laws of physics, this technology of the ‘transport counter’ it can reconstitute a small object through space without any particles crossing it. Among other things, it is a “irrefutable proof” of the existence of a physical reality that supports our most accurate description of the world, reports the University of Bristol it’s a statement.

Physicist Hatim Salih, lead author of the study, honorary research fellow at the University’s Quantum Engineering Technology Laboratories (QET) and co-founder of the company DotQuantum, said: “This is a milestone we have been working towards for many years. It provides a theoretical and practical framework for re-exploring enduring puzzles about the universe, such as the true nature of spacetime.”

The need for detectable information carriers that travel when we communicate has been a deeply held assumption among scientistsFor example, a flow of photons that crosses an optical fiber, or through the air, which allows this text to be read. Or, indeed, the myriad of neural signals that circulate through the brain doing just that.

According to the University of Bristol, this even holds true for quantum teleportation, which, unlike Star Trek, transfers complete information about a small object, allowing it to be reconstituted elsewhere, making it indistinguishable from the original in any meaningful way. . disintegrates. The latter guarantees a fundamental limit that prevents perfect copying. In particular, the recent simulation of a wormhole on Google’s Sycamore processor is essentially a teleportation experiment.

Hatim said, “Here is the sharp distinction. Although countertransportation achieves the ultimate goal of teleportation, namely incorporeal transport, It does this amazingly without any detectable information carrier passing through it.”

Wormholes became popular with the hit movie Interstellar, which featured physicist and Nobel Prize winner Kip Thorne among its team. But they emerged about a century ago as crazy solutions to Einstein’s gravity equation, like shortcuts in the fabric of spacetime. However, the task that defines a traversable wormhole can be summarized as making space disjunctively traversable, i.e., that there is no travel through observable space outside the wormhole.


This pioneering research proposes a way to accomplish this task. “To make countertransport a reality, you need to build an entirely new kind of quantum computer: one without exchange, in which the communicating parts do not exchange particlesHatim explains.

“Unlike large-scale quantum computers, which promise dramatic gains in speed and that no one yet knows how to build, the promise of exchange-free quantum computers, even on the smallest scale, is to make seemingly impossible tasks possible, such as counterportation, fundamentally embodying space along with time”.

In collaboration with leading British quantum experts from Bristol, Oxford and York, this otherworldly wormhole is being planned to be physically constructed in the laboratory.

“The goal in the near future is to physically build a wormhole in the laboratory, that can be used as a testing ground for rival physical theories, including quantum gravityadded Hatim.

“This work will be in the vein of multi-billion dollar companies that exist to witness new physical phenomena, such as the Laser Interferometer Gravitational Wave Observatory (LIGO) and the European Organization for Nuclear Research (CERN), but with a fraction of the resources Our hope is to provide remote access to local wormholes for physicists, physics hobbyists and enthusiasts to explore fundamental questions about the universe, including the existence of higher dimensions.”
