While it can be considered “a filament of real space-time,” according to co-author Daniel Jafferis of Harvard University, lead developer of the wormhole teleportation protocol, it’s not part of the same reality that we and the Sycamore computer inhabit. To be clear, unlike an ordinary hologram, the wormhole isn’t something we can see. “You can think of the system in a very different language as being gravitational.” The evolving system of qubits in the Sycamore chip “has this really cool alternative description,” said John Preskill, a theoretical physicist at Caltech who was not involved in the experiment. Indeed, the new experiment confirms that quantum effects, of the type that we can control in a quantum computer, can give rise to a phenomenon that we expect to see in relativity - a wormhole. Space-time and gravity emerge from quantum effects much as a 3D hologram projects out of a 2D pattern. It says the bendy space-time continuum described by general relativity is really a quantum system of particles in disguise. The holographic principle, ascendant since the 1990s, posits a mathematical equivalence or “duality” between the two frameworks. Physicists have strived since the 1930s to reconcile these disjointed theories - one, a rulebook for atoms and subatomic particles, the other, Einstein’s description of how matter and energy warp the space-time fabric, generating gravity. The experiment can be seen as evidence for the holographic principle, a sweeping hypothesis about how the two pillars of fundamental physics, quantum mechanics and general relativity, fit together. When Spiropulu saw the key signature indicating that qubits were passing through the wormhole, she said, “I was shaken.” With this first-of-its-kind “quantum gravity experiment on a chip,” as Spiropulu described it, she and her team beat a competing group of physicists who aim to do wormhole teleportation with IBM and Quantinuum’s quantum computers. The team, led by Maria Spiropulu of the California Institute of Technology, implemented the novel “wormhole teleportation protocol” using Google’s quantum computer, a device called Sycamore housed at Google Quantum AI in Santa Barbara, California. By manipulating the qubits, the physicists then sent information through the wormhole, they reported today in the journal Nature. The wormhole emerged like a hologram out of quantum bits of information, or “qubits,” stored in tiny superconducting circuits. The tweaking of Newton’s earlier theory enabled Einstein to more accurately define his own theory, which regards the relationship between space and time.Physicists have purportedly created the first-ever wormhole, a kind of tunnel theorized in 1935 by Albert Einstein and Nathan Rosen that leads from one place to another by passing into an extra dimension of space. "He reasoned that if you couldn’t see the background, there’d be no way of knowing that the ball and the feathers were being accelerated towards the Earth. "The “happiest thought of his life” was this the reason the bowling ball and the feather fall together is because they’re not falling. "But Einstein imagined the scene very differently. "Isaac Newton would say that the ball and the feather fall because there’s a force pulling them down: gravity,’ Professor Cox said. His Special Theory of Relativity argued that items would not be falling but standing still due to lack of force acting on them. Professor Cox also used the bowling ball and feather to prove a hypothesis put forward by Albert Einstein. "He took a heavy object, and a light one, and dropped them at the same time to see which fell fastest."Īlthough Galileo’s experiment proved two similarly shaped objects would fall at the same speed despite being different weights, he didn’t have access to a vacuum chamber in the 17th Century to conduct Professor Cox's more extravagant experiment. "Galileo’s experiment was simple," he explains. He alludes to the earlier experiment by Galileo that tested the same hypothesis. In this initial experiment the bowling ball drops straight to the ground whereas the feathers float, owing to air resistance.
