At each level, we first perform an appropriate set of circuit simplifications and then lower the simplified circuit into the next level, decomposing the gates not supported there. We demonstrate its effectiveness, using as a case study the source circuit for Hamiltonian simulation to solve a partial differential equation, which is densely populated with multi-controlled gates and is transformed by the state-","authors_text":"Naoki Yamamoto, Tamiya Onodera, Toshinari Itoko, Yuki Sato","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2025-05-14T12:19:17Z","title":"Multilevel Circuit Optimization in Quantum Compilers: A Case Study"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2505.09320","kind":"arxiv","version":2},"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:d323e6ae1f322fbd1444115193655d7143c9bc43a0c8ff220ec2865f51610f40","target":"record","created_at":"2026-07-05T11:04:01Z","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":"c4ba80773f8d28a1594d0f1f74fade86fd198c49ebaad9221c8118c36cdd036f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2025-05-14T12:19:17Z","title_canon_sha256":"f76deba4468f0b839a31eb71f3ba12e3ed856362906025db496b30280507ffc2"},"schema_version":"1.0","source":{"id":"2505.09320","kind":"arxiv","version":2}},"canonical_sha256":"c7b8481e4f21151a6b5cb9d6758e921b56c4a50629a1d56a645bfd895bf5c604","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c7b8481e4f21151a6b5cb9d6758e921b56c4a50629a1d56a645bfd895bf5c604","first_computed_at":"2026-07-05T11:04:01.086131Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:04:01.086131Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"k9tNtBMJ6VmdKndn/dmCOtCF9bz0rfuBHFzorvNR0WMZolPUjPcr7KQ4bx9Q25fWP8JMULz+5ik3px3BuDx7Bw==","signature_status":"signed_v1","signed_at":"2026-07-05T11:04:01.086753Z","signed_message":"canonical_sha256_bytes"},"source_id":"2505.09320","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d323e6ae1f322fbd1444115193655d7143c9bc43a0c8ff220ec2865f51610f40","sha256:4e3f76e7516c641f8cab82beb9a073dddaf4b4521bd74767a0505195e50784da"],"state_sha256":"142e04d5b41286bd5cc0b7d97b68f451cd908e7e939cab4d2802f5a16ee8537e"}
