Speed limits and locality in many-body quantum dynamics

CFA Chen, A Lucas, C Yin - Reports on Progress in Physics, 2023 - iopscience.iop.org
We review the mathematical speed limits on quantum information processing in many-body
systems. After the proof of the Lieb–Robinson Theorem in 1972, the past two decades have …

Theory of trotter error with commutator scaling

AM Childs, Y Su, MC Tran, N Wiebe, S Zhu - Physical Review X, 2021 - APS
The Lie-Trotter formula, together with its higher-order generalizations, provides a direct
approach to decomposing the exponential of a sum of operators. Despite significant effort …

Dynamical purification phase transition induced by quantum measurements

MJ Gullans, DA Huse - Physical Review X, 2020 - APS
Continuously monitoring the environment of a quantum many-body system reduces the
entropy of (purifies) the reduced density matrix of the system, conditional on the outcomes of …

Quantum information scrambling in a trapped-ion quantum simulator with tunable range interactions

MK Joshi, A Elben, B Vermersch, T Brydges, C Maier… - Physical Review Letters, 2020 - APS
In ergodic many-body quantum systems, locally encoded quantum information becomes, in
the course of time evolution, inaccessible to local measurements. This concept of …

Floquet–Magnus theory and generic transient dynamics in periodically driven many-body quantum systems

T Kuwahara, T Mori, K Saito - Annals of Physics, 2016 - Elsevier
This work explores a fundamental dynamical structure for a wide range of many-body
quantum systems under periodic driving. Generically, in the thermodynamic limit, such …
