Quantum "Magic" and Black Hole Chaos: Unlocking the Origin of Spacetime.

Physicists from RIKEN have suggested that a quantum property called 'magic' may be the key to understanding how spacetime emerged, based on a new mathematical analysis that connects it to the chaotic nature of black holes. The team came across 'magic', which is a mathematical measure of how difficult a quantum state is to simulate using an ordinary classical (non-quantum) computer. Their calculations showed that in a chaotic system almost any state will evolve into one that is 'maximally magical'—the most difficult to simulate. This provides the first direct link between the quantum property of magic and the chaotic nature of black holes.
