The first simulation of a wormhole on a quantum computer made headlines, but a new study brings into question whether it was an accurate representation
30 November 2022
Researchers have used Google's Sycamore quantum computer to simulate a simplified wormhole for the first time, and sent a piece of quantum information through it

It’s the ultimate scientific quest – to understand everything that there is. But the closer we get, the further away it seems. Can we ever get to grips with the true nature of reality?
