Previously, physicists theorized that black holes were the fastest possible information scramblers.

When two quantum objects interact, all the information they carry is scrambled. Physicists have now calculated a fundamental limit on how quickly this can happen.
One notable example of information scrambling occurs in a black hole. Victor Galitsky at the University of Maryland. When objects fall into these ultra-dense objects, some of the information they contain reappears in the black hole’s emitted radiation, but in a highly scrambled form.
In fact, physicists have theorized black holes…
