量子ビットからなる平面表面符号のノイズのある反復的なシンドローム測定をシミュレーションした．その結果，コヒーレントエラーにより論理エラーが増加することを示した．これは，擬確率分布シミュレーションを意味のある課題に実用化したものであり，近未来の量子デバイス上で実験的に量子誤り訂正を研究する上で有用である．","subitem_description_type":"Other"}]},"item_4_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"We propose a sampling-based simulation for fault-tolerant quantum error correction under coherent noise. A mixture of incoherent and coherent noise, possibly due to over-rotation, is decomposed into Clifford channels with a quasiprobability distribution. Then an unbiased estimator of the logical error probability is constructed by sampling Clifford channels with appropriate post-processing. We characterize the sampling cost via the channel robustness and find that the proposed method is feasible even for planar surface codes with relatively large code distances intractable for full state-vector simulations. We simulate repetitive faulty syndrome measurements on the planar surface code of distance 5 with 81 qubits as a demonstration. We find that the coherent error increases the logical error rate. This is a practical application of the quasiprobability simulation for a meaningful task and would be useful to explore experimental quantum error correction on the near-term quantum devices.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"量子ソフトウェア（QS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-10-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"10","bibliographicVolumeNumber":"2021-QS-4"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":213204,"updated":"2025-01-19T17:14:05.980123+00:00","links":{},"created":"2025-01-19T01:14:06.607287+00:00"}
