As a first step toward the laboratory study of quantum gravity, physicists use a quantum computer to monitor wormhole dynamics. Researchers have created the first-ever quantum experiment to investigate the dynamics, or behavior, of a particular type of theoretical wormhole. In order to test a hypothesis of so-called quantum gravity, which states that theoretical wormholes should have linkages to quantum physics, scientists can now perform this experiment. The term “quantum gravity” is used to describe a collection of theories that attempt to reconcile quantum physics with general relativity, two fundamental and well-studied explanations of nature that at first glance appear to be at odds with one another.
The holographic principle, theorized to be a property of quantum gravity, postulates that the description of a volume of space can be encoded on a lower-dimensional boundary.
This research is a preliminary stage in a bigger initiative to put quantum gravity theory to the test on a quantum computer. When compared to future studies that may use quantum sensing to explore quantum gravity phenomena, it is not a suitable replacement for direct probes of quantum gravity. However, it does provide a robust laboratory in which to try out quantum gravity theories.
Wormholes connect seemingly distant parts of space and time. Although their existence and characteristics have not been directly observed, scientists have theorized about them for nearly a century. After Einstein’s general theory of relativity established gravity as a distortion of spacetime, Albert Einstein and Nathan Rosen proposed wormholes in 1935 as tunnels through this fabric. While the name “wormhole” was invented by a scientist named Wheeler in the 1950s, it is more commonly known as “Einstein-Rosen bridges” among researchers.
The current study investigates whether wormholes are analogous to quantum teleportation. The group led by Caltech conducted the first experiments to test the hypothesis that data transmitted through wormholes can be characterized in either the language of gravity or quantum mechanics.
