To realize the encoding scheme, the molecular space is discretized into a 3D grid, and each atom's position and chemical species is mapped to a single computational basis state. This discretization introduces spatial quantization at the voxel-resolution scale. The molecule is then encoded as an equal superposition over this sparse set of occupied states, where we assume that a suitable state p","authors_text":"Antonio Policicchio, Eros De Simone, Giuseppe Bifulco, Lorenza Di Mauro, Raoul Heese","cross_cats":["cs.DS"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2026-07-29T13:55:31Z","title":"Sparse Quantum Voxel Encoding for Readout-Efficient Molecular Geometry Reconstruction on NISQ Devices"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.26925","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":"sha256:361ad284051bcf0bf00d1eee0f3d81999d215d1ac0046fce6ad64c28e078b774","target":"record","created_at":"2026-07-30T01:23:02Z","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":"c56b373ff9ecff19633c075d0a07968f3c4ba242d05d2b6b893eb653c480b991","cross_cats_sorted":["cs.DS"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2026-07-29T13:55:31Z","title_canon_sha256":"84b18954809099800911e8694ddcad880693e0bb7779ed5c6d0d0fe2780c3673"},"schema_version":"1.0","source":{"id":"2607.26925","kind":"arxiv","version":1}},"canonical_sha256":"d23759fd812f11cc4934f9da646a96546107a14819cd8540097193e1ffba175d","receipt":{"builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d23759fd812f11cc4934f9da646a96546107a14819cd8540097193e1ffba175d","first_computed_at":"2026-07-30T01:23:02.163168Z","kind":"pith_receipt","last_reissued_at":"2026-07-30T01:23:02.163168Z","receipt_version":"0.3","signature_status":"unsigned_v0"},"source_id":"2607.26925","source_kind":"arxiv","source_version":1}}},"equivocations":[{"signer_id":"pith.science","event_type":"integrity_finding","target":"integrity","event_ids":["sha256:1b70538c273ab28687bff7a790c6fd568d9849b424ca9205a9287ed423e33ad7","sha256:371e116ca35deda3d2ece1103ea5bb490d3f6ea219362ead52ad02590abb39bc"]}],"invalid_events":[],"applied_event_ids":["sha256:361ad284051bcf0bf00d1eee0f3d81999d215d1ac0046fce6ad64c28e078b774","sha256:4464234a4e9ef4096c8b12f790fc3667160cfda4213082cd1f73982fdebdaaba"],"state_sha256":"1a10440458d480fafab6c7c9615cafb3c6ebf78766cdef8d2adef152203a8d70"},"bundle_signature":{"signature_status":"signed_v1","algorithm":"ed25519","key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signature_b64":"H81yX+tNT2FGSCZaRdVi8u78pgQUo5jy8C4UcVuq2p3FHvMOr+BhEnZvFMkr4yvtRCLTwoWM3eJLWqX9+qPyCQ==","signed_message":"bundle_sha256_bytes","signed_at":"2026-08-09T18:29:28.203472Z","bundle_sha256":"276bf3f6d10bafe227ff98f405d362d67c106343031367b1e139e21468fa2451"}}
