"Researchers have discovered that complex random behaviors naturally emerge from even the simplest, chaotic dynamics in a quantum simulator. This illustration zooms into one such complex set of states within an apparently smooth quantum system.

A qubit is a particle that has multiple states. And the biggest problem in quantum systems is the energy flow. The energy level in the qubit must be different than in the background. There is a possibility that the qubit's energy level is higher or lower than its background. In the image from the top of the text, you can see the problem with the background. The energy background in nature has different levels. And that thing can cause that when qubit travels over those energy pits that affects the energy level ...
