The discovery of topological order has revised the understanding of quantum matter and provided the theoretical foundation for many quantum error-correcting codes. Realizing topologically ordered states has proven to be challenging in both condensed... Read More about Realizing topologically ordered states on a quantum processor.

Orthogonal Quantum Many-Body Scars (2021)
Journal Article
Zhao, H., Smith, A., Mintert, F., & Knolle, J. (2021). Orthogonal Quantum Many-Body Scars. Physical Review Letters, 127(15), Article 150601. https://doi.org/10.1103/PhysRevLett.127.150601

Quantum many-body scars have been put forward as counterexamples to the eigenstate thermalization hypothesis. These atypical states are observed in a range of correlated models as long-lived oscillations of local observables in quench experiments sta... Read More about Orthogonal Quantum Many-Body Scars.

Skeleton of matrix-product-state-solvable models connecting topological phases of matter (2021)
Journal Article
Jones, N. G., Bibo, J., Jobst, B., Pollmann, F., Smith, A., & Verresen, R. (2021). Skeleton of matrix-product-state-solvable models connecting topological phases of matter. Physical Review Research, 3(3), Article 033265. https://doi.org/10.1103/physrevresearch.3.033265

Models whose ground states can be written as an exact matrix-product state (MPS) provide valuable insights into phases of matter. While MPS-solvable models are typically studied as isolated points in a phase diagram, they can belong to a connected ne...

Topological two-dimensional Floquet lattice on a single superconducting qubit (2021)
Journal Article
Malz, D., & Smith, A. (2021). Topological two-dimensional Floquet lattice on a single superconducting qubit. Physical Review Letters, 126(16), Article 163602. https://doi.org/10.1103/PhysRevLett.126.163602

Current noisy intermediate-scale quantum (NISQ) devices constitute powerful platforms for analogue quantum simulation. The exquisite level of control offered by state-of-the-art quantum computers make them especially promising to implement time-depen...

The current generation of noisy intermediate-scale quantum computers introduces new opportunities to study quantum many-body systems. In this paper, we show that quantum circuits can provide a dramatically more efficient representation than current c...

Butterfly effect and spatial structure of information spreading in a chaotic cellular automaton (2021)
Journal Article
Liu, S.-W., Willsher, J., Bilitewski, T., Li, J.-J., Smith, A., Christensen, K., Moessner, R., & Knolle, J. (2021). Butterfly effect and spatial structure of information spreading in a chaotic cellular automaton. Physical Review B, 103(9), Article 094109. https://doi.org/10.1103/physrevb.103.094109

Inspired by recent developments in the study of chaos in many-body systems, we construct a measure of local information spreading for a stochastic cellular automaton in the form of a spatiotemporally resolved Hamming distance. This decorrelator is a... Read More about Butterfly effect and spatial structure of information spreading in a chaotic cellular automaton.
