Based on a linearly interacting spin-boson model, we show that the multi pulse application recovers the decay of concurrence when an entangled pair of spins interacts with a reservoir that has the non-Markovian nature. We present the effectiveness of multi pulse control for both the common bath case and the individual bath case.","authors_text":"Chikako Uchiyama, Masaki Aihara","cross_cats":[],"headline":"","license":"","primary_cat":"quant-ph","submitted_at":"2004-12-08T07:25:14Z","title":"Multi pulse control of entanglement"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"quant-ph/0412062","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:d87e05c20ff4a3aad0bcdbc2245f6100b930b6444308cc8dee272dbe68898562","target":"record","created_at":"2026-07-04T14:46:52Z","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":"7cdca3a6c5146dc061b323fea1025a69e5c315bab80d02268a135c8f853a9652","cross_cats_sorted":[],"license":"","primary_cat":"quant-ph","submitted_at":"2004-12-08T07:25:14Z","title_canon_sha256":"8d0f8fb38eec049f15f3bb9d845c208d0684771d597ed0f0e3ef2ca28a735245"},"schema_version":"1.0","source":{"id":"quant-ph/0412062","kind":"arxiv","version":1}},"canonical_sha256":"99c56b2a22e779df3c0a4ee957f1ecf635d3c7e14265e89805e53c3e10177776","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"99c56b2a22e779df3c0a4ee957f1ecf635d3c7e14265e89805e53c3e10177776","first_computed_at":"2026-07-04T14:46:52.670536Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T14:46:52.670536Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"v5awl2oBWIFV+nbr9TiZTcXri3S3R8p+Rru8CoXNTs6U/XUUsQdo0VSQdhhdKvgrIx0NI4K8xVvoOQoqTcs4Aw==","signature_status":"signed_v1","signed_at":"2026-07-04T14:46:52.670986Z","signed_message":"canonical_sha256_bytes"},"source_id":"quant-ph/0412062","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d87e05c20ff4a3aad0bcdbc2245f6100b930b6444308cc8dee272dbe68898562","sha256:b66fb1195bca6f31a236c811a40d024f80cab584526b8ad7e480555d5f946330"],"state_sha256":"f57c26c3da15a4a7e9dcd950a889a7a7be6d6c7fcd24b9bf6e5cda07b7aff2b6"}
