Universal Decay of Mutual Information and Conditional Mutual Information in Gapped Pure- and Mixed-State Quantum Matter
Jinmin Yi, Kangle Li, Chuan Liu +2
For spin and fermionic systems in any spatial dimension, we establish that the superpolynomial decay behavior of mutual information and conditional mutual information is a universa…

Experimental violation of a Bell-like inequality for causal order
Yu Guo, Hao Tang, Bo-Xuan Wang +9
Quantum mechanics is compatible with scenarios where physical processes happen in an indefinite order. In theory, this feature could be detected through violations of inequalities…

Geometric quantum drives and topological dynamical responses: hyperbolically-driven quantum systems and beyond
Jihong Wu, Chuan Liu, Daniel Bulmash +1
We introduce a geometrical framework to construct a large class of time-dependent quantum systems, in which the position of a classical particle moving autonomously on a smooth con…
