Did a real wormhole show up in a quantum computer a few months ago? That depends on what you mean by “real”: Physicists are still divided as to what the result means.

At the end of last year, a team led by Harvard physicist Daniel Jafferis published in the magazine Nature a job, which caused a stir not only in the professional world. The story contains practically everything that makes the heart of science fiction fans beat faster: wormholes, quantum computers, black holes and the search for the “world formula”. Even holograms play a role. But what all this really means and what follows from it – physicists are still at odds about this.
