While the implementation of quantum read-only memory (QROM) is a bottleneck of QSVT, it has been difficult to optimize and estimate the resource of QROM due to its complexity. In this paper, we present a novel software framework that enables a flexible description of complicated modules of FTQC such as a QROM. Then, we describe a QROM module with our framework and perform circuit optimization by ZX-calculus. As a result, we observed a 35% reduction of required T-depth. Based on the result, we also estimate the time and space required for demonstrating the computational supremacy with QSVT.","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":"2022-03-17","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"2022-QS-5"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
