Symmetry-Protected Infinite-Temperature Quantum Memory from Subsystem Codes
Julia Wildeboer, Thomas Iadecola, Dominic J. Williamson
We study a mechanism whereby quantum information present in the initial state of a quantum many-body system can be protected for arbitrary times due to a combination of symmetry an…

Rainbow Scars: From Area to Volume Law
Christopher M. Langlett, Zhi-Cheng Yang, Julia Wildeboer +3
Quantum many-body scars (QMBS) constitute a new quantum dynamical regime in which rare "scarred" eigenstates mediate weak ergodicity breaking. One open question is to understand th…
