摘要
我们提出并考察了几种多体纠缠普适度量的候选方案。对于需要在全希尔伯特空间中纠缠的应用，最有前景的候选者是 ent-concurrence（纠缠并发度），它可探测所有纠缠关联，同时区分不同类型的独特多体纠缠，并且对于两量子比特混合态简化为 concurrence（并发度）。对于子系统需要内部纠缠的应用，我们发展了绝对 ent-concurrence（绝对纠缠并发度），它可探测约化态以及全态中的纠缠。

备注
16 pages, 9 figures. v2: changed "nonlocal correlations" to "entanglement correlations" since that is what was meant and is more accurate since it distinguishes them from nonlocal correlations not involving entanglement. v3: incorporated new term "full k-partite entanglement" defined as "the absence of k-separability" for compatibility with existing terminology.
