Bridging Classical and Quantum Information Scrambling with the Operator Entanglement Spectrum
Ben T. McDonough, Claudio Chamon, Justin H. Wilson +1
Universal features of chaotic quantum dynamics underlie our understanding of thermalization in closed quantum systems and the complexity of quantum computations. Reversible automat…
Calderbank-Shor-Steane codes on group-valued qudits
Ben T. McDonough, Jian-Hao Zhang, Victor V. Albert +1
Calderbank-Shor-Steane (CSS) codes are a versatile quantum error-correcting family built out of commuting - and -type checks. We introduce CSS-like codes on -valued qudits…
Lieb-Robinson bounds with exponential-in-volume tails
Ben T. McDonough, Chao Yin, Andrew Lucas +1
Lieb-Robinson bounds demonstrate the emergence of locality in many-body quantum systems. Intuitively, Lieb-Robinson bounds state that with local or exponentially decaying interacti…
Non-perturbatively slow spread of quantum correlations in non-resonant systems
Ben T. McDonough, Marius Lemm, Andrew Lucas
Strong disorder often has drastic consequences for quantum dynamics. This is best illustrated by the phenomenon of Anderson localization in non-interacting systems, where destructi…
