Summary

New constructions include [[90,21,11]], [[140,31,15]] and [[200,43,20]] parameter sets.

The preprint presents ultra-high-rate quantum LDPC code families and analyzes their logical performance at a 0.1% physical error rate. Those figures are code and noise-model results, not measurements from a fabricated quantum processor.

Why it matters

New constructions include [[90,21,11]], [[140,31,15]] and [[200,43,20]] parameter sets.

Limits and context

  • Those figures are code and noise-model results, not measurements from a fabricated quantum processor.

Key claims

  1. New constructions include [[90,21,11]], [[140,31,15]] and [[200,43,20]] parameter sets.

    Qualification: Those figures are code and noise-model results, not measurements from a fabricated quantum processor.
