Scientists Reportedly Use Quantum Computer to Reverse Time

A team of scientists from Russia, Switzerland and the US claims to have reversed the flow of time with an IBM quantum computer.Published in scientific report , the study also theorizes that an electron in empty interstellar space will spontaneously travel back into its recent past.

According to the researchers, the study done at the Moscow Institute of Physics and Technology explored the possibility of developing protocols for reversing the 'arrow of time' in a direct contradiction to the second law of thermodynamics, which states that the universe's disorder, or entropy, can only grow, or at best, remain constant under thermodynamic equilibrium, but never decrease over time.
