It is known that the probability distribution of measurement results on three output qubits of the one-clean-qubit model cannot be classically efficiently sampled within a constant multiplicative error unless the polynomial-time hierarchy collapses to the third level [T. Morimae, K. Fujii, and J.\u2009F. Fitzsimons, Phys. Rev. Lett. 112, 130502 (2014)]. It was open whether we can keep the no-go result while reducing the number of output qubits from three to one. Here, we solve the open problem affirmatively. We also show that the third-level collapse of the polynomial-time hierarchy can be strengthened to the second-level one. The strengthening of the collapse level from the third to the second also holds for other subuniversal models such as the instantaneous quantum polynomial model [M. Bremner, R. Jozsa, and D.\u2009J. Shepherd, Proc. R. Soc. A 467, 459 (2011)] and the boson sampling model [S. Aaronson and A. Arkhipov, STOC 2011, p. 333]. We additionally study the classical simulatability of the one-clean-qubit model with further restrictions on the circuit depth or the gate types.", "subitem_description_type": "Abstract"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1103/PhysRevLett.120.200502", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2018 American Physical Society "}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_61": {"attribute_name": "ISSN\uff08print\uff09", "attribute_value_mlt": [{"subitem_source_identifier": "0031-9007", "subitem_source_identifier_type": "ISSN"}]}, "item_10_source_id_62": {"attribute_name": "ISSN\uff08Online\uff09", "attribute_value_mlt": [{"subitem_source_identifier": "1079-7114", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Fujii, Keisuke"}], "nameIdentifiers": [{"nameIdentifier": "87258", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kobayashi, Hirotada"}], "nameIdentifiers": [{"nameIdentifier": "87259", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Morimae, Tomoyuki"}], "nameIdentifiers": [{"nameIdentifier": "87260", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nishimura, Harumichi"}], "nameIdentifiers": [{"nameIdentifier": "87261", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tamate, Shuhei"}], "nameIdentifiers": [{"nameIdentifier": "87262", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tani, Seiichiro"}], "nameIdentifiers": [{"nameIdentifier": "87263", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-11-01"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "PhysRevLett120_200502.pdf", "filesize": [{"value": "201.0 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 201000.0, "url": {"label": "PhysRevLett120_200502", "url": "https://nagoya.repo.nii.ac.jp/record/26544/files/PhysRevLett120_200502.pdf"}, "version_id": "f04346ee-55b1-487b-838f-85bf1840a17f"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Impossibility of Classically Simulating One-Clean-Qubit Model with Multiplicative Error", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Impossibility of Classically Simulating One-Clean-Qubit Model with Multiplicative Error"}]}, "item_type_id": "10", "owner": "1", "path": ["312/313/314"], "permalink_uri": "http://hdl.handle.net/2237/00028747", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_name_i18n": "\u516c\u958b\u65e5", "attribute_value": "2018-11-01"}, "publish_date": "2018-11-01", "publish_status": "0", "recid": "26544", "relation": {}, "relation_version_is_last": true, "title": ["Impossibility of Classically Simulating One-Clean-Qubit Model with Multiplicative Error"], "weko_shared_id": null}
