Topics covered include: single-copy and asymptotic entanglement manipulation; the entanglement of formation; the entanglement cost; the distillable entanglement; the relative entropic measures; the squashed entanglement; log-negativity; the robustness monotones; the greatest cross-norm; uniqueness and extremality theorems. Infinite dimensional systems and multi-party settings will be discussed briefly.","external_url":"https://arxiv.org/abs/quant-ph/0504163","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-25T16:01:02.207590+00:00","pith_arxiv_id":"quant-ph/0504163","created_at":"2026-05-10T10:14:10.508568+00:00","updated_at":"2026-06-05T21:23:00.469572+00:00","title_quality_ok":false,"display_title":"An introduction to entanglement measures","render_title":"An introduction to entanglement measures"},"hub":{"state":{"work_id":"a1d0d580-0875-4934-88cc-d2bfe323ebd6","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":12,"external_cited_by_count":null,"distinct_field_count":4,"first_pith_cited_at":"2019-06-26T09:24:44+00:00","last_pith_cited_at":"2026-05-17T10:38:52+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-06-06T10:00:52.427271+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":7}],"polarity_counts":[{"context_polarity":"background","n":7}],"runs":{},"summary":{},"graph":{},"authors":[]}}
