The initial-value problem of the Schroedinger equation is solved non-perturbatively for the system of a free electron interacting with a quantized mode of the electromagnetic radiation. Wave packets of the dressed states so obtained are constructed in order to describe the spatio-temporal separation of the subsystems before and after the interaction. The joint probability amplitudes are calculated for the detection of the electron at some space-time location ","authors_text":"Sandor Varro","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2009-10-25T19:51:36Z","title":"Entangled States and Entropy Remnants of a Photon-Electron System"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0910.4764","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":"sha256:94cdf10fe9a0cfece93120e9c73c23ee9a5dff33c8c84e0bf3930ae5ebeec808","target":"record","created_at":"2026-05-18T04:39:59Z","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":"bf4481e7939d80f1023a553b2959662e62c3336638f78322b68dd40056f6aec1","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2009-10-25T19:51:36Z","title_canon_sha256":"0657f1e23ba1f490bad1678db0ff2a311d2e2b522eb83c7ee3e37cdba6b948cf"},"schema_version":"1.0","source":{"id":"0910.4764","kind":"arxiv","version":1}},"canonical_sha256":"e44f3228f345eee9afd47f32bea3650a3f5ce1107ff128f622437e527513a74c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e44f3228f345eee9afd47f32bea3650a3f5ce1107ff128f622437e527513a74c","first_computed_at":"2026-05-18T04:39:59.440300Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:39:59.440300Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"8g6T4/RBB+4z7yCsTpTW4phDx42qmosJKGXCCa/7fqUQCgbqOkIqwOcmmZOykRT9nTuwTgHrCAddkaMac/iODQ==","signature_status":"signed_v1","signed_at":"2026-05-18T04:39:59.440867Z","signed_message":"canonical_sha256_bytes"},"source_id":"0910.4764","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:94cdf10fe9a0cfece93120e9c73c23ee9a5dff33c8c84e0bf3930ae5ebeec808","sha256:1aa7395677784238e8b8b048c89aec43a51b106552660b183671cd77f0f5195e"],"state_sha256":"faf6cb23d5e933305428b27a5b5ef59a37e600b20f1806e23e965f60b74dbca9"}
