Simulating quantum 'time travel' disproves butterfly effect in quantum realm: Evolving quantum processes backwards on a quantum computer to damage information in the simulated past causes little change when returned to the 'present'

Using a quantum computer to simulate time travel, researchers have demonstrated that, in the quantum realm, there is no 'butterfly effect.' In the research, information--qubits, or quantum bits--'time travel' into the simulated past.
