According to the laws of physics that we know, one process cannot return to its original state after another. Even if you try to force it, it will only come back at a different time. In this experiment, it was concluded that the computer had returned to its original state and that the time index had returned to its original state, in other words, it was able to pull back time. According to analysts, this is only 85% successful, and only if only three of the Qubit particles return to their original state will it be 50% successful.
