>> It’s important to point out, though, that the experiment comes with all kinds of caveats. The wormholes the group were simulating, and indeed, even the holographic principle on which they’re based, exist in a hypothetical kind of universe that operates very differently from our own. In addition, their experiments assumed only two dimensions: one spatial dimension and the dimension of time.

>> “The relationship between quantum entanglement, spacetime, and quantum gravity is one of the most important questions in fundamental physics and an active area of theoretical research,” Spiropulu said.

Experiment is done in two dimensions but the physicists describe an experiment which is valid in “spacetime" which must have 4 dimensions.

It looks like there is a disconnect between theory and the experiment.
