Deep thermalization and Hilbert space ergodicity
Daniel K. Mark, Manuel Endres, Matteo Ippoliti +2
Recent advances in quantum simulation have enabled the discovery of novel forms of universality in quantum many-body dynamics. In this Review, we discuss deep thermalization and Hi…
Emergent universality in Kraus maps of quantum chaotic many-body dynamics
Qi Camm Huang, Wai-Keong Mok, Tobias Haug +1
Recent studies of "deep thermalization" have revealed universal physics in quantum many-body dynamics beyond equilibration towards Gibbs states: maximally random quantum state ense…
Quantum resource localizability transitions in deep thermalization
Xiaozhou Feng, Chang Liu, Zihan Cheng +2
We investigate how quantum resource constraints affect deep thermalization, the emergence of universal local wavefunction distributions from partial measurements of a quantum many-…
Nature is stingy: Universality of Scrooge ensembles in quantum many-body systems
Wai-Keong Mok, Tobias Haug, Wen Wei Ho +1
Recent advances in quantum simulators allow direct experimental access to ensembles of pure states generated by measuring part of an isolated quantum many-body system. These projec…
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…
Coherence-induced deep thermalization transition in random permutation quantum dynamics
Chang Liu, Matteo Ippoliti, Wen Wei Ho
We report a phase transition in the projected ensemble - the collection of post-measurement wavefunctions of a local subsystem obtained by measuring its complement. The transition…
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]…
Deep thermalization in Gaussian continuous-variable quantum systems
Chang Liu, Qi Camm Huang, Wen Wei Ho
We uncover emergent universality arising in the equilibration dynamics of multimode continuous-variable systems. Specifically, we study the ensemble of pure states supported on a s…
Hilbert-Space Ergodicity in Driven Quantum Systems: Obstructions and Designs
Saúl Pilatowsky-Cameo, Iman Marvian, Soonwon Choi +1
Despite its long history, a canonical formulation of quantum ergodicity that applies to general classes of quantum dynamics, including driven systems, has not been fully establishe…
Solvable entanglement dynamics in quantum circuits with generalized space-time duality
Chuan Liu, Wen Wei Ho
We study the non-equilibrium dynamics of kicked Ising models in dimensions which have interactions alternating between odd and even bonds in time. These models can be underst…
Complete Hilbert-Space Ergodicity in Quantum Dynamics of Generalized Fibonacci Drives
Saúl Pilatowsky-Cameo, Ceren B. Dag, Wen Wei Ho +1
Ergodicity of quantum dynamics is often defined through statistical properties of energy eigenstates, as exemplified by Berry's conjecture in single-particle quantum chaos and the…
Nonlocality of Deep Thermalization
Harshank Shrotriya, Wen Wei Ho
We study the role of global system topology in governing deep thermalization, the relaxation of a local subsystem towards a maximally-entropic, uniform distribution of post-measure…
Universal measurement-based quantum computation in a one-dimensional architecture enabled by dual-unitary circuits
David T. Stephen, Wen Wei Ho, Tzu-Chieh Wei +2
A powerful tool emerging from the study of many-body quantum dynamics is that of dual-unitary circuits, which are unitary even when read `sideways', i.e., along the spatial directi…
Solvable model of deep thermalization with distinct design times
Matteo Ippoliti, Wen Wei Ho
We study the emergence over time of a universal, uniform distribution of quantum states supported on a finite subsystem, induced by projectively measuring the rest of the system. D…
Dynamical purification and the emergence of quantum state designs from the projected ensemble
Matteo Ippoliti, Wen Wei Ho
Quantum thermalization in a many-body system is defined by the approach of local subsystems towards a universal form, describable as an ensemble of quantum states wherein observabl…
