The complexity of interparticle interaction and environment coupling increases rapidly with the number of to-be-entangled subsystems, rendering the requirements on the control of many-body quantum systems ever more restrictive. We propose an approach that allows to derive optimal control Hamiltonians in a purely algebraic fashion. These drive a composite quantum system rapidly into that highly entangled state which can be created most efficiently for a given interaction mec","authors_text":"Andreas Buchleitner, Felix Platzer, Florian Mintert","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2009-10-26T15:48:56Z","title":"Optimal dynamical control of many-body entanglement"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0910.4908","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":"sha256:47e3374f6db905631f13dfc86de2ef60bc867f56903e803edad884c186ea272d","target":"record","created_at":"2026-05-18T03:12:58Z","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":"31cba91e334457496412c7f789006142c90bb2bac5043dec3ea857769337db68","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2009-10-26T15:48:56Z","title_canon_sha256":"29f958ebec91deca37ca5838c8190fbf86f63e25d32859775251bbe00bae5a4e"},"schema_version":"1.0","source":{"id":"0910.4908","kind":"arxiv","version":1}},"canonical_sha256":"530b7f435448c719bac9207aeed9a823cc0a6519c71cc031b56bc2e677c555ba","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"530b7f435448c719bac9207aeed9a823cc0a6519c71cc031b56bc2e677c555ba","first_computed_at":"2026-05-18T03:12:58.300306Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:12:58.300306Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"75tzDJ3iSUeYIwhe+9eR0xbNr9ChMs16Ki57cQtS0iwJYLWv7Hs39av80ssfKoNCiaM/N88PuupCqouatigGAA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:12:58.301094Z","signed_message":"canonical_sha256_bytes"},"source_id":"0910.4908","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:47e3374f6db905631f13dfc86de2ef60bc867f56903e803edad884c186ea272d","sha256:c827aa2fd99135bfe83e6efd3849d36808f31085a77b9b74e2518a11d5ddc2f1"],"state_sha256":"50b493a38d13aecfc0daf4c0b1d60df0639f3407ccf07cca85ad1b9800291ca5"}
