QUANTUM COMPUTERS👇
A quantum computer used by scientists in Russia has been able to send a single electron back in time, enabling the computer to be reset from a moment earlier
Fall Back
In an experiment conducted on a quantum computer, Russian scientists appear to have reversed the flow of time.
There is little chance that the findings would lead to a human-powered time machine. IBM's public quantum computer was restored to its previous state by researchers published Wednesday in the journal Nature Scientific Reports — a nuanced result, but one that could have striking implications for computing, quantum physics, as well as our understanding of time.
“We have artificially created a state that evolves in a direction opposite to that of the thermodynamic arrow of time,” Gordey Lesovik, a quantum physicist from the Moscow Institute of Physics and Technology who led the research project, said in a university-published press release.
Great Scott
About 85 percent of the time, the quantum computer was able to obtain its original state after physicists worked with simplifed, two-qubit systems. The time reversal experiment only worked 49 percent of the time with a more complex quantum computer with three qubits.
Likewise, this study has nothing to do with a time-traveling machine, just as research into quantum teleportation is not related to transporting people. By kicking back through time, the scientists hope to be able to double check what quantum computer scientists are doing with their software..
Very good info
