‘Wormhole’ built on teleported information by quantum computer as predicted – ScienceAlert

For the first time, scientists have created one quantum computing experiment to study the dynamics of wormholes, that is, shortcuts in spacetime that could bypass the cosmic speed limits of relativity.

Wormholes are traditionally the stuff of science fiction, ranging from Jodie Foster’s Wild Ride contact to the The timebending plot twists interstellar. But the researchers behind the experiment, reported in the December 1 issue of the magazine Naturethey hope their work will help physicists study the phenomenon for real.

“We have found a quantum system that exhibits key properties of a gravitational wormhole, but is small enough to be implemented in today’s quantum hardware,” said Caltech physicist Maria Spiropulu. he said in a press release. Spiropoulos, the Nature lead author of the paper, is the principal investigator of a federally funded research program known as Quantum communication channels for fundamental physics.

Don’t pack your bags for Alpha Centauri just yet: this wormhole simulation is just a simulation, analogous to a computer generated black hole or supernova

And physicists still don’t see any conditions under which a traversing wormhole can actually be created. Someone should create negative energy first

Columbia theoretical physicist Peter Woit cautioned against doing too much to do with research.

“The claim that ‘Physicists create a wormhole’ is total bullshit, with the massive campaign to mislead the public about it is a disgrace, very unhelpful to the credibility of physics research in particular and science Generally”. he wrote on his blogwhich is called Not Even Bad.

The main objective of the research was to shed light on a concept known as a quantum gravitywhich aims to unify the theories of general relativity and quantum mechanics.

These two theories have done an excellent job of explaining how gravity works and how the subatomic world is structured, respectively, but they don’t agree well with each other.

One of the big questions centers on whether wormhole teleportation can follow the principles behind quantum entanglement.

This quantum phenomenon is better understood, and has even been demonstrated in the real world, thanks to Nobel Prize-winning research: It involves linking subatomic particles or other quantum systems in a way that allows what Albert Einstein called “creepy action at a distance.”

Spiropulu and his colleagues, including lead authors Daniel Jafferis and Alexander Zlokapa, created a computer model that applies the physics of quantum entanglement to the dynamics of wormholes.

His program was based on a theoretical framework known as a Sachdev-Ye-Kitaev modelor SYK.

The big challenge was that the program had to run in a as much as a computer. from Google Sycamore quantum processing chip it was powerful enough to take on the task, with an assist from the conventionals machine learning tools.

“We have provided work [machine] “Learning techniques to find and prepare a simple SYK-like quantum system that could be encoded in current quantum architectures and would preserve gravitational properties”, Spiropulu. said.

“In other words, we simplified the microscopic description of the SYK quantum system and studied the resulting effective model that we found in the quantum processor.”

The researchers inserted a quantum bit, or qubit, of coded information into one of the two entangled systems, then watched the information emerge from the other system. From their perspective, it was as if the qubit passed between them black holes through a wormhole.

“It took a long time to get to the results and we were surprised with the result.” said Caltech researcher Samantha Davis, one of the study’s co-authors.

The team found that the wormhole simulation allowed information to flow from one system to another when the computerized equivalent of negative energy was applied, but not when positive energy was applied. This matches what theorists would expect from a real-world wormhole.

As quantum circuits become more complex, researchers aim to perform higher-fidelity simulations of wormhole behavior, which could lead to new twists on fundamental theories.

“The relationship between quantum entanglement, spacetime, and quantum gravity is one of the most important questions in fundamental physics and an active area of ​​theoretical research,” Spiropulu. said.

“We’re excited to take this small step to test these ideas on quantum hardware, and we’re going to move forward.”

In addition to Jafferis, Zlokapa, Spiropulu and Davis, the authors of the Nature paper, titled “Dynamics of traversing wormhole in a quantum processor”, includes Joseph Lykken, David Kolchmeyer, Nikolai Lauk and Hartmut Neven.
