of_q_qec_mwpm

Minimum-weight perfect matching accelerator

Maturity plannedTargets FPGA + ASICDifficulty Very hardPriority 2

Hardware-assisted sparse blossom matching on the detector graph for higher-accuracy decoding of surface and repetition codes.

Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.

Interfaces
