Magic
A group of real-life scientists at the RIKEN Interdisciplinary Theoretical and Mathematical Sciences in Japan have identified a new quantum property to measure the weirdness of spacetime. They are officially calling it “magic.”
From the scientific paper, “Probing chaos by magic monotones,” published by the journal Physical Review D:
There is a property of a quantum state called “magic.” As shown by the Gottesman-Knill theorem, so-called stabilizer states, which are composed of only Clifford gates, can be efficiently computed on a classical computer, and thus quantum computation gives no advantage. Nonstabilizer states are called magic states, which are necessary to achieve the universal quantum computation. Magic (monotone) is the measure of the amount of nonstabilizer resource, and it measures how difficult it is for a classical computer to simulate the state. We study magic of states in the integrable and chaotic regimes of the higher-spin generalization of the Ising model through two quantities: “mana” and “robustness of magic” (RoM). We find that in the chaotic regime, mana increases monotonically in time in the early-time region, and at late times these quantities oscillate around some nonzero value that increases linearly with respect to the system size. Our result also suggests that under chaotic dynamics, any state evolves to a state whose mana almost saturates the optimal upper bound; i.e., the state becomes “maximally magical.”
And this bit:
Our results suggest that magic of quantum states is strongly involved in the emergence of spacetime geometry.
That last sentence is the best technobabble I’ve heard in a long time. Sounds like something the Doctor in an episode of Doctor Who would say.
