If this is true , humans have entered the twilight zone

An international team of scientists claims to have reversed time with the help of a quantum computer.

By using electrons and quantum mechanics researchers claim they were able to turn back time in an experiment likened to causing a broken rack of pool balls to roll back into place.

The experiment used quantum computer programs to ‘rewind’ scattered quantum bits or qubits back to their starting points.

Researchers from the Moscow Institute of Physics and Technology, helped by colleagues in Switzerland and the U.S., expect the technique to become more efficient.
 
The quotation marks around "reversed time" are very important here. Here's the actual breakdown taken from user DreamyPants on reddit:

  • This reversal was not performed in a closed system, but was instead driven by a specific device.

  • The second law of thermodynamics still holds in general for closed systems.

  • The flow of time was not ever actually reversed in this system, however a quantum states evolution was successfully reversed. Its cool and useful, but it's not time travel.
