This paper investigates an entanglement-distillation protocol for a two-dimensional qubit array that allows nearest-neighbor interactions. To distill the pair of entangled qubits without losing their fidelities in a 2D-integrated qubit array, we need to minimize the number of operations to let qubits be close to another one. We present an efficient protocol for 2D-integrated qubits by reducing the optimization problem into the graph matching problems. We also numerically show the performance of our protocol and its dependency on the device parameters.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"10","bibliographic_titles":[{"bibliographic_title":"量子ソフトウェア（QS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-03-17","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"32","bibliographicVolumeNumber":"2022-QS-5"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
