Then each quantum operation $\\Phi_B$ on the quantum system $\\cH_B$ can induce a quantum ensemble $\\set{(p_\\mu,\\rho_{A,\\mu})}$ on quantum system $\\cH_A$. In this paper, we show that the Holevo quantity $\\chi\\set{(p_\\mu,\\rho_{A,\\mu})}$ of the quantum ensemble $\\set{(p_\\mu,\\rho_{A,\\mu})}$ can be upper bounded by both subsystem entropies. By using the result, we answer partly a conjecture of Fannes, de Melo, Roga and \\.{Z}yczkowski.","authors_text":"Junde Wu, Lin Zhang, Shao-Ming Fei","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2011-10-27T03:58:35Z","title":"Universal upper bound for the Holevo information induced by a quantum operation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1110.5979","kind":"arxiv","version":3},"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":"sha256:690fc4d2465a3242e77598bd0d7bf256acd19806689b05950ca1bf6a097a4ec2","target":"record","created_at":"2026-05-18T03:41:11Z","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":"a2637f89865aed9548413cf3e277c9d973cf2d78f2b5fb11020934f4f40c9218","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2011-10-27T03:58:35Z","title_canon_sha256":"4d405552b43c34efac19de9b8fca2e1cda8971184a0c63e92da7be6b897dd55f"},"schema_version":"1.0","source":{"id":"1110.5979","kind":"arxiv","version":3}},"canonical_sha256":"f790c62a534283a4d5e27664bd2de5b5d5eea3a3abb0a5af98953b0c4fdf4420","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f790c62a534283a4d5e27664bd2de5b5d5eea3a3abb0a5af98953b0c4fdf4420","first_computed_at":"2026-05-18T03:41:11.021244Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:41:11.021244Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"f4IqoASb2Di+NC0NGvb4fWrw/Ei24qKDEHGEMX9NEYs2qgnz1wBjRCpWxhcH+aPg3X2RVbZksI1uWOKeS+HHCA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:41:11.021923Z","signed_message":"canonical_sha256_bytes"},"source_id":"1110.5979","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:690fc4d2465a3242e77598bd0d7bf256acd19806689b05950ca1bf6a097a4ec2","sha256:49bb86dfdd1247efcc68bbe97baf3c86e02978e229995d2b56f31a991c02ae63"],"state_sha256":"855f18458424bc6ca99ebe0416c582e5631d79f6d972ca34e7116db7c6310635"}
