Claims in many media outlets that this experiment has turned fiction into reality are overstatements. Scientists did not bring a wormhole into actual physical existence — they merely used Google's 72-qubit Sycamore 2 quantum processor to establish a quantum system which could exhibit the key properties of a gravitational wormhole.
Per comments from the Caltech researchers, there is still a long way to go before we can send humans or animals through an artificially fabricated portal. However, this trial has made a key step forward in experimental science by successfully finding a way to explore the fundamental ideas of our universe in a laboratory setting. Additionally, wormhole simulation in a quantum computer adds weight to the holographic principle of the universe. This experiment is a huge development.
