Physicists simulated a wormhole using a quantum computer

For the first time, physicists have simulated a wormhole using a quantum computer. In fact, the experiment did not create a real wormhole, rather it will allow them to study the connections between these theoretical spacetime tunnels and quantum physics. The aim is to establish a connection between gravity and quantum physics, two apparently incompatible descriptions of nature.

Is quantum teleportation possible?

Wormholes are "bridges" between two remote regions of spacetime. We have never observed them, but scientists have been theorizing about them for almost 100 years. In 1935, Albert Einstein and Nathan Rosen described them as wormholes that traverse spacetime: that’s why they were also nicknamed "Einstein-Rosen bridges", while the term wormhole was coined by physicist John Wheeler in the 1950s.

The new study examines the relationship between wormholes and quantum teleporting. The idea is that information that travels from one point to another in space can be described in the language of gravity or quantum physics. In particular, physicists observed the dynamics of the wormhole on a Google quantum device. During the experiment the researchers inserted a qubit, the quantum equivalent of a bit, into one of their systems at SYK and observed that the information was traveling from one system to another, like a real quantum teleportation.
