We introduce the concept of nested topological order in a class of exact quantum lattice Hamiltonian models with non-Abelian discrete gauge symmetry. The topological order present in the models can be partially destroyed by introducing a gauge s[...]texto impreso
Andrist, Ruben S. ; Bombin, H. ; Katzgraber, Helmut G. ; Martín-Delgado Alcántara, Miguel Ángel | American Physical Society | 2012-05-14A promising approach to overcome decoherence in quantum computing schemes is to perform active quantum error correction using topology. Topological subsystem codes incorporate both the benefits of topological and subsystem codes, allowing for er[...]texto impreso
Bombin, H. ; Ruben, S. Andrist ; Masayuki, Ohzeki ; Katzgraber, Helmut G. ; Martín-Delgado Alcántara, Miguel Ángel | American Physical Society (APS) | 2012-04-30The inevitable presence of decoherence effects in systems suitable for quantum computation necessitates effective error-correction schemes to protect information from noise. We compute the stability of the toric code to depolarization by mapping[...]texto impreso
Andrist, Ruben S. ; Katzgraber, Helmut G. ; Bombin, H. ; Martín-Delgado Alcántara, Miguel Ángel | IOP Publishing | 2011-08-08We compute the error threshold of color codes—a class of topological quantum codes that allow a direct implementation of quantum Clifford gates—when both qubit and measurement errors are present. By mapping the problem onto a statistical–mechani[...]texto impreso
Ohzeki, Masayuki ; Thomas, Creighton K. ; Katzgraber, Helmut G. ; Bombin, H. ; Martín-Delgado Alcántara, Miguel Ángel | IOP Publishing | 2011-02-01We study the effects of disorder on the slope of the disorder–temperature phase boundary near the Onsager point (T_(c) = 2.269 . . .) in spin-glass models. So far, studies have focused on marginal or irrelevant cases of disorder. Using duality a[...]
