Our analysis focuses on resource costs for simulating both time-independent and time-dependent Hamiltonians. For the time-independent case, we benchmark PMR against quantum signal processing (QSP) and qubitization, using the Rydberg interaction Hamiltonian as a representative example. For the time-dependent case, we compare the time-dependent extension of PMR with the quantum highly oscillatory protocol (qHOP), applied to a Floquet-driven t","authors_text":"Hriday Sabharwal, Itay Hen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2026-05-28T02:58:41Z","title":"Permutation Matrix Representation for Quantum Simulation: Comparative Resource Analysis"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.29279","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:ea3899097467fcf9163a33dd95a62923e08cf09a96d17258d5de7e821bc4442b","target":"record","created_at":"2026-05-29T01:05:28Z","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":"753a95766398fc418d55077dc28b12223be12fe3bc5fc5c8328406364695d983","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2026-05-28T02:58:41Z","title_canon_sha256":"86348165c6d1895f1ba0eb87141c4b33bdba3a6ffbf9f443db2c71a9ca8ae51a"},"schema_version":"1.0","source":{"id":"2605.29279","kind":"arxiv","version":1}},"canonical_sha256":"82bd5dd0edbe851c0007a5b6b2a948beb0e490defe1a7f826f878e4487cc4f22","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"82bd5dd0edbe851c0007a5b6b2a948beb0e490defe1a7f826f878e4487cc4f22","first_computed_at":"2026-05-29T01:05:28.793922Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-29T01:05:28.793922Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qvpOudqSqlpt8srqQLV9r+VvIzqcE0Q9fg1z9rhwWThoEjURojc1k7203yrkvQScC1XnuElSHn164IC43+8yAA==","signature_status":"signed_v1","signed_at":"2026-05-29T01:05:28.794700Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.29279","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ea3899097467fcf9163a33dd95a62923e08cf09a96d17258d5de7e821bc4442b","sha256:283b5020ba219993b66b83c3f89ebc5c86e4ff19b798c7c98a6b4373fd742fdf"],"state_sha256":"1622186cefd8691090ab7e27dd00e486e96148b6277a6ecd20f7fca77d4fbde5"}
