These scientists managed to “return the time”: how is it possible?

In the macroscopic physical world in which we live, we must all see with our mistakes. A thousand times we wished the authorities Return in timeBut the reality is such that this is impossible, and the sooner we assume this, the better. However, if we were Subatomic particlesanother rooster sang to us, since the team of scientists from Vienna University and Austrian Academy of SciencesWith Spanish Miguel Navasquez Among them, he discovered that in the quantum world he could return back in time.

This is due to duality, which particles usually have in this quantum world. We all heard about Schrödinger’s mental experiment, in which the cat is alive and dead at the same time, because particles that should break a bottle of poison in his box may have Overlapping states and cross it or not. In this case, a kind Quantum switch, in which you can act on All possible particle trajectories And choose the one that, according to the visible, has already passed.

This could not be transferred to a macroscopic scale. That is why we cannot return to the past to cancel our mistakes. But, if the experiment can be reproduced, this can help get even more for celebrities Quantum computersSince their errors can get rid of. These conclusions are for the first time ahead. Or behind, depending on how you look.

How does the time switch work?

Quantum switch developed by these scientists Analyze all the conditions through which the photon of light passes, moving through the crystal. Then choose any of them, even if they took place earlier.

This does not overwhelm the film, as it cannot be seen. When we rewind the film, we see images on a quick chamber in front of our eyes, moves back. In this case, this simply returns to the previous state, but you cannot cancel the path for the simple reason that in quantum physics Simple observation of the system makes it a change. That is why SHCROEDINGER said that the cat will be alive or dead until the box has opened. At the moment when we opened it and observed its interior, the floor of particles in several conditions would simultaneously get rid of everything, and only one state will choose everything. Here, if we look at the process, everything will be changed and will not be able to reach this previous point. With the help of a quantum switch, he simply searched for the system to be solved in relation to the point that has already occurred.

The future of quantum computers

Thanks to this ability to return in quantum weather Errors could be turned back on a subataulic scaleField quantum computers that can process a lot of information at the same time, They will become even more effectiveThe field would also be a great step forward of artificial intelligence, since quantum computers are necessary for automatic training to another level. The advantages in areas such as climatic modeling or the search for new drugs would be huge.

Therefore, although we can still cancel the moment when we agree with this toxic pair or reject this work that would like us in the background, return in quantum time It can also be very useful for us. Not bad at all.
