Probably why it says 'simuate' in the title and in several places in the article...?
To be fair its not a good piece, it's clickbait and doesn't really explain the experiment. The work had two purposes: to explore Leonard Susskind's idea that quantum entanglement and the wormholes in General Relativity are somehow the same thing; and to test some ideas on whether it would be (theoretically) possible to stabilise a wormhole long enough to travel through one.
