No feasible architecture exists to implement the high-order optimization problem (K > 2) on current quantum annealing hardware. We propose a two-dimensional quantum annealing architecture to solve the 4th order binary optimization problem by encoding four-qubit interactions within the coupled local fields acting on a set of physical qubits. All possible four-body coupling terms for an N-qubit system can be implemented through this architecture and are readil","authors_text":"Guo-Xing Miao, Yong-Chao Tang","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2016-05-12T16:46:04Z","title":"2D implementation of quantum annealing algorisms for fourth order binary optimization problems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1605.03887","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":"sha256:6f5ae0962b8a1c82d65a3cb69c9cc619a552f6891a08a7caa407c68af57ed6e1","target":"record","created_at":"2026-05-18T01:14:59Z","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":"9c95967417a0d7d265ade3acbe9e1560c52a160c3c36971c7af850852efde073","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2016-05-12T16:46:04Z","title_canon_sha256":"b6b3ad699881ea2210a7bb11eec43df3cf60955fdf84f8da67e25d16f45e601c"},"schema_version":"1.0","source":{"id":"1605.03887","kind":"arxiv","version":1}},"canonical_sha256":"bad27d75c6b44db15a5ff9a46d33da45a3903962a2fc85dfa835466b3ccee662","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bad27d75c6b44db15a5ff9a46d33da45a3903962a2fc85dfa835466b3ccee662","first_computed_at":"2026-05-18T01:14:59.286950Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:14:59.286950Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"RkCLK1cHl6CDsGMdQSzUPW266iqJPQWf4YiHTZ6AGRR4/cMlw8Ta5XXluXNNjvRDcC04iUUC4B2y5++lhxXGAg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:14:59.287583Z","signed_message":"canonical_sha256_bytes"},"source_id":"1605.03887","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6f5ae0962b8a1c82d65a3cb69c9cc619a552f6891a08a7caa407c68af57ed6e1","sha256:7f5e58ae837e2337bf2188d1b56612410551bb83b0056b177e852fec22b14b65"],"state_sha256":"ddbbeb3309c83e3c3338ce48c77f85656095c4fd16b1e8b0ff9b321f5144834e"}
