Abstract(in English) | Error correction is mandatory to realize a quantum computer that can perform practical calculations. Surface codes is one of typical error correction methods because of their high error correction capability. In this study, we designed an error decoder, which is a part of the error correction function, using Verilog HDL. The greedy algorithm is used in the design. The designed HDL was synthesized in a 22-nm bulk process to evaluate performance, power and area. Its area and power consumption are also evaluated by changing the number of nodes that can be stored in the decoder. As a result, it is confirmed that the circuit can operate up to 1 GHz with 40 entries. The area and power consumption were $mathrm{5.85mu m^2}$ and $mathrm{4.28mW}$, respectively. |
