In this paper, motivated by the limited precision of quantum solvers, we develop the first IR scheme for solving semidefinite optimization (SDO) problems and explore two major impacts of the proposed IR scheme. First, we prove that the proposed IR scheme exhibits quadratic convergence toward an optimal solution without any assumption on problem characteristics. We also show that using IR with Quantum Interior Point Methods ","authors_text":"Brandon Augustino, Mohammadhossein Mohammadisiahroudi, Pouya Sampourmahani, Tam\\'as Terlaky","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"math.OC","submitted_at":"2023-12-18T14:51:15Z","title":"Quantum Computing Inspired Iterative Refinement for Semidefinite Optimization"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2312.11253","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:88ab813affb477d1c4e61f6c6dbed4928d4b8e1d33d73509d646566cf54b80a7","target":"record","created_at":"2026-07-05T07:25:30Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"1cc7599ba50607f38721a23deeb1d8bc515af9cb56f52dc13cbd9b62caf53ee5","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"math.OC","submitted_at":"2023-12-18T14:51:15Z","title_canon_sha256":"d53f9c41405bbbc1ea3a35c5c58b7723c8fc6896c691b07234458193bcfb32bd"},"schema_version":"1.0","source":{"id":"2312.11253","kind":"arxiv","version":1}},"canonical_sha256":"fbb5b335f8b53e572aaa251d65eec3f12d6685c203c205578b46e89568d41fd4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"fbb5b335f8b53e572aaa251d65eec3f12d6685c203c205578b46e89568d41fd4","first_computed_at":"2026-07-05T07:25:30.467090Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:25:30.467090Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1ujo2wh6S/gDbbS5sW8j3t2VfNGe0fkgK19vzGhijzBiFoJPZ7zV3Qpihvz8FhFK9TW9QV83BvbR0v3uy4n1CQ==","signature_status":"signed_v1","signed_at":"2026-07-05T07:25:30.467589Z","signed_message":"canonical_sha256_bytes"},"source_id":"2312.11253","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:88ab813affb477d1c4e61f6c6dbed4928d4b8e1d33d73509d646566cf54b80a7","sha256:d15453f101f4810d1efe2cc8424e1c61ba065c92c80fbcd757147ffecce2d6b0"],"state_sha256":"d4786378cc73e839438acc38b21fcdc9dc86b2860f34df56f8e5e931020c4fa2"}
