In particular, surface code (SC) has attracted attention as one of the most promising error-correcting codes. In this study, we have designed an RTL surface code decoder using the iterative greedy algorithm to implement on NanoBridge-FPGA that can operate in cryogenic environments. The designed decoder was verified using the same error simulator as in the previous study, and latency and resource usage were also evaluated. In addition, we performed logic synthesis, placement and routing targeting NanoBridge-FPGA and confirmed the resource usage.}, pages = {13--25}, title = {極低温不揮発FPGAを対象とした誤り耐性量子コンピュータ向け表面符号復号器のRTL設計}, volume = {17}, year = {2024} }
