Circuit-level benchmarks of GKP-concatenated qLDPC Codes
Results show that analog GKP information continues to improve decoding under circuit-level noise, with analog-informed belief-propagation with ordered-statistics decoding (BP-OSD) yields higher finite-size crossing estimates than hard-decision decoding.
