Scalable tests of quantum contextuality from stabilizer-testing nonlocal games
Wanbing Zhao, H. W. Shawn Liew, Wen Wei Ho +2
Soon after the dawn of quantum error correction, DiVincenzo and Peres observed that stabilizer codewords could give rise to simple proofs of quantumness via contextuality. This dis…
Temporal entanglement transition in chaotic quantum many-body dynamics
Ilya Vilkoviskiy, Michael Sonner, Qi Camm Huang +3
Temporal entanglement (TE) of an influence matrix (IM) has been proposed as a measure of complexity of simulating dynamics of local observables in a many-body system. Foligno et al…
Observation of hierarchy of Hilbert space ergodicities in the quantum dynamics of a single spin
Wenquan Liu, Zouwei Pan, Yue Fu +4
Ergodicity, the property that all allowed configurations are explored over time, plays a pivotal role in explaining the equilibrium behavior of classical dynamical systems. Yet, su…
Mixed state deep thermalization
Xie-Hang Yu, Wen Wei Ho, Pavel Kos
We introduce the notion of the mixed state projected ensemble (MSPE), a collection of mixed states describing a local region of a quantum many-body system, conditioned upon measure…
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…
Critically Slow Hilbert-Space Ergodicity in Quantum Morphic Drives
Saúl Pilatowsky-Cameo, Soonwon Choi, Wen Wei Ho
The maximum entropy principle is foundational for statistical analyses of complex dynamics. This principle has been challenged by the findings of a previous work [arXiv:1701.07596]…
