Just the other day I was reading an article about the butterfly effect in quantum mechanics and how the butterfly effect has been proven not to exist

i know of it from chaos theory. how was the idea adapted to quantum physics?

In 2020, researchers at Los Alamos National Laboratory experimentally proved that the “butterfly effect” does not exist in quantum mechanics. In order to simulate the “butterfly effect” and find out whether it exists, scientists used a quantum computer. They sent to the “past” information - quantum bits or qubits, and then severely damaged one of them. That is, they actually repeated what the hero of Ray Bradbury's famous story did by stepping on a butterfly. However, further in the experiment, everything went quite different from the story. When the cubes were returned to the “present”, they appeared undamaged - as if reality had self-recovered. Does this make the “butterfly effect” not work? 1/2

2/2 “On a quantum computer, there is no problem with simulating time-reversed evolution or running processes back in time,” says Nikolai Sinitsyn, one of the study's co-authors, a theoretical physicist at Los Alamos Laboratory. - That is, we can actually see what happens to a complex quantum world if we traveled back in time, cause a little damage and come back. We found that our world in this case will be preserved, and this means that the “butterfly effect” in quantum mechanics does not exist” The damage done in the past, as Sinitsyn and his co-author Bing Yang found out, causes only local and insignificant changes in the present. The conclusion is one - the “butterfly effect” does not exist. And this discovery has not only theoretical, but also quite practical application.

thanks! fascinating that they used quantum computation to prove something critical to... quantum computation. as i understand it, quantum effects decohere as your approach "macro" objects (ie, our scale) and prediction of any kind depends on this emergent "order."

According to Yang, it turns out that information damaged due to third-party sensing in the entangled state can then be easily recovered, since this damage does not increase with the decoding process. Of course, this technology is still at an early stage of development, but it has great potential. The main thing, that I think, is that it would be directed in the right direction, for example medicine and its development, and not on weapons of mass destruction
