String order parameters for symmetry fractionalization in an enriched toric code
José Garre-Rubio, Mohsin Iqbal, David T. Stephen
We study a simple model of symmetry-enriched topological order obtained by decorating a toric code model with lower-dimensional symmetry-protected topological states. We show that…
Subsystem symmetry enriched topological order in three dimensions
David T. Stephen, José Garre-Rubio, Arpit Dua +1
We introduce a model of three-dimensional (3D) topological order enriched by planar subsystem symmetries. The model is constructed starting from the 3D toric code, whose ground sta…
Inaccessible entanglement in symmetry protected topological phases
Caroline de Groot, David T. Stephen, Andras Molnar +1
We study the entanglement structure of symmetry-protected topological (SPT) phases from an operational point of view by considering entanglement distillation in the presence of sym…
Detecting subsystem symmetry protected topological order via entanglement entropy
David T. Stephen, Henrik Dreyer, Mohsin Iqbal +1
Subsystem symmetry protected topological (SSPT) order is a type of quantum order that is protected by symmetries acting on lower-dimensional subsystems of the entire system. In thi…
Subsystem symmetries, quantum cellular automata, and computational phases of quantum matter
David T. Stephen, Hendrik Poulsen Nautrup, Juani Bermejo-Vega +2
Quantum phases of matter are resources for notions of quantum computation. In this work, we establish a new link between concepts of quantum information theory and condensed matter…
A computationally universal phase of quantum matter
Robert Raussendorf, Cihan Okay, Dong-Sheng Wang +2
We provide the first example of a symmetry protected quantum phase that has universal computational power. Throughout this phase, which lives in spatial dimension two, the ground s…
