Ultrahigh threshold nonstabilizer nonlinear quantum error correcting code
Researchers have proposed a new family of quantum error-correcting codes that are neither stabilizer codes nor linear. The codes exhibit an ultrahigh error threshold, potentially exceeding those of standard surface and other stabilizer codes. This work was posted as a preprint on arXiv.

Theoretical validation of this code on noisy intermediate-scale quantum devices could begin within two years, potentially demonstrating error suppression at error rates where stabilizer codes fail.
The ultrahigh threshold makes it compatible with near-term devices; the main gating factor is implementing the non-stabilizer operations robustly on existing hardware.
