The analysis is performed using both Hartree--Fock canonical molecular orbitals (CMOs) and Pipek--Mezey-based localized molecular orbitals (LMOs). For short hydrogen chains, we evaluate the ground-state energy and fidelity and find that, in the CMO-based wave function expansion, introducing a threshold on Hamil","authors_text":"Hiroyuki Tezuka, Kenji Sugisaki, Masayoshi Terabe, Yuhei Tachi","cross_cats":["physics.chem-ph"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2026-08-05T06:08:47Z","title":"Impact of molecular orbital localization on quantum computational resources for Hamiltonian simulation: A benchmark study of hydrogen chain systems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2608.04481","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":"sha256:90959addaee422e995cca7891719d37d5871993fc1c9b58a0ad1a82619649cc2","target":"record","created_at":"2026-08-06T01:35:41Z","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":"6953ebc3a7254cfcc48b8345d4743777f19796af825c3e94cc96a3ee2afe2360","cross_cats_sorted":["physics.chem-ph"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2026-08-05T06:08:47Z","title_canon_sha256":"45b2c542aec44ee214ff6171791d8f821bd003f5f60d848db1d78e2b2640821c"},"schema_version":"1.0","source":{"id":"2608.04481","kind":"arxiv","version":1}},"canonical_sha256":"98ab660ca28784e2e670d783f83f2c9f22ea2e8a613f8564ff9bfd0704cc7417","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"98ab660ca28784e2e670d783f83f2c9f22ea2e8a613f8564ff9bfd0704cc7417","first_computed_at":"2026-08-06T01:35:41.251175Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-08-06T01:35:41.251175Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xUSydxSsBmajNGcVkj1NyZmMhDqLwgB6SfUtq2KlHYRdBoz7zoaBDJnWwiFjslCfEsYnwEAWNWTV/lkBgC+/DQ==","signature_status":"signed_v1","signed_at":"2026-08-06T01:35:41.252644Z","signed_message":"canonical_sha256_bytes"},"source_id":"2608.04481","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:90959addaee422e995cca7891719d37d5871993fc1c9b58a0ad1a82619649cc2","sha256:c927b69d4e39e2d3b3dd8bae2f3d235dfc30314d9e80d1107285007131c25a17"],"state_sha256":"f21f9dcd8e6382eb0b4a1169b354d4446234673f9a1b1307803d0fa1605b826e"}
