In our research, TP are two qubits and SP are two qubits or qutrits. When TP are two qubits, we find that no matter what state the TP is initially prepared in, at the specific time $t=\\pi$, the entanglement of TP can attain to 1 after interaction with SP which stay on the maximally entangled state. For the TP are two qutrits, we find that the maximal entanglement of TP after interaction is relative to the initial state of TP and always ","authors_text":"Fu-Lin Zhang, Jing-Ling Chen, Qing-You Meng","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-11-24T12:02:48Z","title":"Quantum Entanglement transfer between spin-pairs"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1011.5352","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":"sha256:29ad1d5682d71fbc51f5775ee8e907c97b94b48b4294d051d1f4408f19131ef1","target":"record","created_at":"2026-05-18T04:11:39Z","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":"eae7c532dbca37d2e53f57d8d189f05aefcf137ac7640f62a95991ada8fafcbd","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-11-24T12:02:48Z","title_canon_sha256":"f506d25060195656c37f70cab812f846128571dd7dd2cb743834d49c67cfc0fd"},"schema_version":"1.0","source":{"id":"1011.5352","kind":"arxiv","version":2}},"canonical_sha256":"065ec9b78df456625863613f79e4826f3be575aa9a847fbab08f8d96499cd6dd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"065ec9b78df456625863613f79e4826f3be575aa9a847fbab08f8d96499cd6dd","first_computed_at":"2026-05-18T04:11:39.674918Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:11:39.674918Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BQIHAkV9CDNdA8VcIJPjdxE+efoa8L00GBl32nkxxUbXtfzVN9fti1Cn3+nAZdkxIhT5oWAYuQrbAOunSp+rBw==","signature_status":"signed_v1","signed_at":"2026-05-18T04:11:39.675569Z","signed_message":"canonical_sha256_bytes"},"source_id":"1011.5352","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:29ad1d5682d71fbc51f5775ee8e907c97b94b48b4294d051d1f4408f19131ef1","sha256:22e659624061f42e80a5ef4113a9559c796459a107a79975952bf30d04900312"],"state_sha256":"80441fc9d8df1f1cb960d5f9b7a4b36f5b801527e50a5a2b18114654161163d0"}
