Research: the butterfly effect does not exist in the quantum model

Scientists at Los Alamos National Laboratory used a quantum computer and simulated a time travel model. They found that the butterfly effect did not exist in their experiment.

The researchers used a quantum computer to simulate time travel and showed that there is no butterfly effect in the quantum model. They used quantum bits and sent them to a simulated past. In this case, one of the bits was damaged during sending, but it did not damage other bits that were sent along with them.

The simulation involved two hypothetical humans, Alice and Bob, each with a qubit – a quantum bit of information. During the experiment, Alice sent her qubit to the past, but at some point, Bob intervened in it and changed the information in it. However, despite the changes, Alice was able to recover the information when the qubit returned.

This way we can really see what happens to the complex quantum world if we travel through time, add a little damage and come back. We found that this does not harm the present, which means there is no butterfly effect in quantum mechanics.

The researchers repeated the experiment and found that simulating the return of a qubit to the past and inflicting damage on it has little or no effect on the information it carries. This effect can be applied in areas where quantum devices must carry secret information. Data can be hidden by transforming the original state into a confusing one.

“We found that even if an attacker manipulates in a highly entangled state, we can still easily recover useful information since this damage does not increase with decoding,” the scientists noted.
