"We have artificially created a state that evolves in a direction opposite to that of the thermodynamic arrow of time," said Gordey Lesovik, head of the Quantum Information Physics Laboratory at MIPT and lead author of the study.
The scientists used a quantum computer composed of "qubits" of electrons.
A qubit is an information unit composed of a "one", a "zero" or an "overlap" of both states.
The computer used an "evolution program" that made the qubits, over time, take on an increasingly complex changing pattern of zeros and ones.
Another program was also used that modified the state of the quantum computer in such a way that it evolved "backwards", from chaos to order. That is, he managed to get the qubits back to how they were initially.
But does not this contradict the laws of physics? From the point of view of quantum mechanics, the past and the future are so similar that they can be interchangeable, to the point that most of the laws of physics do not admit temporary distinctions, because they work exactly the same regardless of time. is moving forward or backward
However, the Universe has a law that goes in only one direction: the Second Law of Thermodynamics, which describes the progression of order to disorder.
But this innovative experiment has not dismantled the Second Law of Thermodynamics. And the authors explain that this advance is disturbing, but that there are still many more studies and still much more time to start talking about travel in time, but that in the future they can be done, we do not know, but there are great possibilities that something like this happens
What do you think is an interesting discovery? Do you think we can travel through time in the not so distant future? Leave us your answer in the comments. See you soon! 🤯😜🤪
