Physicists observe wormhole dynamics using a quantum computer
For the first time, scientists have developed a quantum experiment that allows them to study the behavior of a special kind of theoretical wormhole.
The experiment doesn't create an actual wormhole, rather it allows researchers to probe connections between theoretical wormholes and quantum physics, a prediction of so-called quantum gravity.
The principal investigator of the U.S., says that a quantum system that exhibits key properties of a wormhole is small to implement on today's quantum hardware.
Einstein's general theory of relativity describes gravity as a curvature of spacetime, and wormholes were described as tunnels through the fabric of spacetime.
The term "wormhole" was invented by physicist John Wheeler in the 1950s, while researchers call Einstein–Rosen bridges after the two physicists who invoked them.
The idea that wormholes and quantum physics may have a connection was first proposed in theoretical research by Juan Maldacena and Leonard Susskind in 2013.
The scientists came up with a scenario in which negative repulsive energy holds a wormhole open long enough for something to pass through from one end to the other.
In quantum teleportation, a protocol that has been demonstrated over long distances via optical fiber and over the air, information is transported across space using the principles of quantum
Gao et. al described that the model's quantum Two other researchers who worked on the development of the model suggested that some theoretical wormhole ideas could be studied more deeply.
In the experiment, the researchers inserted a qubit, the quantum equivalent of a bit in conventional Silicon-based computers, into one of their SYK-like systems and observed the information emerge from the other system.
They observed the dynamics of the wormhole on a quantum device at the same time they used a "baby" SYK-like model to preserve gravitational properties.
The information traveled from one quantum system to the other via quantum teleportation, or, speaking in the complimentary language of gravity, the quantum information passed through the traversable wormhole.
we had to simplify the quantum system to the smallest example that preserves gravitational characteristics so we could implement it on the Sycamore quantum processor.
