Ergodicity breaking provably robust to arbitrary perturbations
David T. Stephen, Oliver Hart, Rahul M. Nandkishore
We present a new route to ergodicity breaking via Hilbert space fragmentation that displays an unprecedented level of robustness. Our construction relies on a single emergent (pret…
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…
Fractionalization of subsystem symmetries in two dimensions
David T. Stephen, Arpit Dua, José Garre-Rubio +2
The fractionalization of global symmetry charges is a striking hallmark of topological quantum order. Here, we discuss the fractionalization of subsystem symmetries in two-dimensio…
