The surface-GKP code has a fault-tolerance threshold of 11.2 dB GKP squeezing when only GKP states are noisy, 0.81% per-component failure when GKP states are ideal, and 18.6 dB with 0.69% when both are noisy.

Fault-tolerant bosonic quantum error correction with the surface-GKP code
The surface-GKP code has a fault-tolerance threshold of 11.2 dB GKP squeezing when only GKP states are noisy, 0.81% per-component failure when GKP states are ideal, and 18.6 dB with 0.69% when both are noisy.
