Duality between string and computational order in symmetry-enriched topological phases
Paul Herringer, Vir B. Bulchandani, Younes Javanmard +2
We present the first examples of topological phases of matter with uniform power for measurement-based quantum computation. This is possible thanks to a new framework for analyzing…
Sequential Quantum Circuits as Maps between Gapped Phases
Xie Chen, Arpit Dua, Michael Hermele +4
Finite-depth quantum circuits preserve the long-range entanglement structure in quantum states and map between states within a gapped phase. To map between states of different gapp…
Charting the space of ground states with tensor networks
Marvin Qi, David T. Stephen, Xueda Wen +4
We employ matrix product states (MPS) and tensor networks to study topological properties of the space of ground states of gapped many-body systems. We focus on families of states…
Renormalization of Ising cage-net model and generalized foliation
Zongyuan Wang, Xiuqi Ma, David T. Stephen +2
A large class of type-I fracton models, including the X-cube model, have been found to be fixed points of the foliated renormalization group (RG). The system size of such foliated…
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…
