The first simulation of a wormhole on a quantum computer may not be an accurate representation of a wormhole after all. Since the original simulation was announced last year, another group of researchers has examined the physics behind the work and found several issues that could spoil the results.

At the center of the original work is a concept called a “3D wormhole”, which is a depiction of a wormhole that has been simplified using techniques from quantum mechanics to make it easier to simulate. More importantly , …
