Operationally, we show that a single round of such a generalized measurement eliminates quasiprobability negativity in finite-dimensional systems. From the decoherence perspective, this loss of negativity occurs abruptly at a critical time. In particular, this critical time can be shorter than the conventional decoherence time, indicating that the latter does not always faithf","authors_text":"Zhenyu Xu","cross_cats":["cond-mat.stat-mech"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2025-07-17T14:38:30Z","title":"Quantum-to-Classical Transition via Single-Shot Generalized Measurements"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2507.13174","kind":"arxiv","version":3},"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:b4f132e92ce4d638842a706bc196bdfc7a02f10a63df0f761c38da40826f1520","target":"record","created_at":"2026-06-03T01:05:05Z","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":"a58387ad6f73db7cb93788bb987f3a17a086ba677dc19c9454aeaa1f201ad178","cross_cats_sorted":["cond-mat.stat-mech"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2025-07-17T14:38:30Z","title_canon_sha256":"7a3d40dd50a8e126a752d985069ee34af31696c9591be6f99779e46bca81b338"},"schema_version":"1.0","source":{"id":"2507.13174","kind":"arxiv","version":3}},"canonical_sha256":"3ad1a6eff39a02507bddf94622bb11ac2a63b3d2a12dc029d380f1187a2b0f32","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3ad1a6eff39a02507bddf94622bb11ac2a63b3d2a12dc029d380f1187a2b0f32","first_computed_at":"2026-06-03T01:05:05.136559Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-03T01:05:05.136559Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"tPvdZBIM5jJPXurcgWJ3YqMMRj8QGhJ2I4vyE0TSwsVZutGn2uf/4JmbUhDMjuVZOEfqBYkVmQnic75uNnKVBg==","signature_status":"signed_v1","signed_at":"2026-06-03T01:05:05.137135Z","signed_message":"canonical_sha256_bytes"},"source_id":"2507.13174","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b4f132e92ce4d638842a706bc196bdfc7a02f10a63df0f761c38da40826f1520","sha256:ce95fef9c5966bcce979661f76e0e2f76ef2bd1485b187c21d1f917f5d3e5c95"],"state_sha256":"c4ae41592b51895e4cf8ebd7c9cf828137d9fa4f5ef96258b9f3f46e8209f12e"}
