Abstract

Toward Quantum Computing: Quantum computers are expected to be able to tackle problems that would take classical computers many lifetimes to solve. Nonabelian states of matter can store quantum information in their topology, making them immune to environmental perturbations. A physical system expected to possess this unusual property is the fractional quantum Hall state at filling factor ν = 5/2. Tiemann et al. (p. 828 , published online 26 January) used nuclear magnetic resonance to measure the polarization of the 5/2 state and found that it is fully polarized—a finding consistent with a nonabelian state—keeping hopes for topological fault-tolerant quantum computing alive.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
