As a consequence, the quantum world appears to us paradoxical. Here we shed new light on QT by being based on two main postulates: 1. the theory should be logically consistent; 2. inferences in the theory should be computable in polynomial time. The first postulate is what we require to each well-founded mathematical theory. The computation postulate defines the physical component of the theory. We show that the computation postulate is the only true divide between QT, see","authors_text":"Alessandro Facchini, Alessio Benavoli, Marco Zaffalon","cross_cats":["cs.CC","math.OC"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2019-02-12T09:38:45Z","title":"Computational Complexity and the Nature of Quantum Mechanics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1902.04569","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":"sha256:56c250f8c78ab231d6521d8cfb48d73193a65266fc7541a599ab92faf309dff4","target":"record","created_at":"2026-05-17T23:45:52Z","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":"f7daa2afb92bd00c1c85602a6d2a0daadec7b617ce367fc8e4c4f492dfceef1a","cross_cats_sorted":["cs.CC","math.OC"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2019-02-12T09:38:45Z","title_canon_sha256":"b73f4cbfc19fd9ae6f82eb7ac10ebe9600fb62a567c41979feef35b41576f56c"},"schema_version":"1.0","source":{"id":"1902.04569","kind":"arxiv","version":2}},"canonical_sha256":"2554116ec0a99f7df5cf63f31e18d00a8fe0af87bca23be9a45e6dddbaa773dc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2554116ec0a99f7df5cf63f31e18d00a8fe0af87bca23be9a45e6dddbaa773dc","first_computed_at":"2026-05-17T23:45:52.060944Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:45:52.060944Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1qLbPWxzJlDZkTonKDP4gOGpWNZHFug1MhxnBGlqhRGYWe+hY3GwTY/SssKMziV3kAxHLtheMq2JAvBxwf0ZDA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:45:52.061424Z","signed_message":"canonical_sha256_bytes"},"source_id":"1902.04569","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:56c250f8c78ab231d6521d8cfb48d73193a65266fc7541a599ab92faf309dff4","sha256:c4ccd4526e75950550a2b8da8d51450695ffb10c1c4b225154b5c705a0c8f772"],"state_sha256":"f6a4bf36656213507490b4348ce38349e3422924c3972e0192b98b7491e7efaa"}
