Scientists have figured a way to time travel.
Growing up, time travel has been the stuff of science fiction for most of us. An idea so far fetched that even the writers of popular sci-fi universe of Star Trek treat it as a technology far beyond the capability of man — and alien — kind. However, in the real world, a few Moscow-based scientists may just have found a way to achieve what remains incomprehensible even for many science fiction writers.
In what could be a stepping stone for one of the greatest scientific achievements of our generation, a team of scientists from the Moscow Institute of Physics and Technology (MIPT) has used a powerful quantum computer to successfully simulate the reversal of time.
As per a report published in the Nature Journal, these scientists used an IBM Quantum computer to run an experiment where two qubits were allowed to evolve and reach a certain developed quantum state before being brought back to their original state a second ago. As the report explains, scientists first evolved these qubits and then were able to successfully bring them back to the state they were in before the experiment started.
The feat was achieved using a complex quantum algorithm which was run thousands of times and achieved an 85% success rate of reverting the qubits to their original state. Now why the reversal of the qubits is so interesting is because these quantum bits are known to only move forward with the passing of time. As such, for them to defy the concept “Arrow of Time” which states that time only moves forward is quite revolutionary.
Are we truly close to achieving time travel?
However impressive this feat may be, we should not delude ourselves into believing that humankind has figured out time travel. In fact, the truth is far from it.
The bottom line is that this was but a simulation carried out inside a controlled environment within a quantum computer. A thought even echoed by a member of the team that achieved the scientific breakthrough. Speaking to CNN, Gordey Lesovik of the MIPT explained that “we’re not really” approaching the ability to actually reverse time.
However, there is still no denying how important this achievement is in theory. We may not be close to sending people back in time, but we appear to have finally embarked on a journey to achieve this.
