摘要

量子纠缠在量子信息处理中起着举足轻重的作用。量子纠缠的量化是该领域一个具有挑战性和必要的研究领域。本文探讨了二部纠缠并发、多部纠缠并发和真正的多部纠缠并发之间的关系。我们从这些关系中导出了GME并发性的下界，并通过严格的证明和数值例子证明了它们比现有结果的优越性。此外，我们还研究了多部量子系统中GME并发与其他纠缠度量（如缠结和全局负性）之间的联系。

A note on the lower bounds of genuine multipartite entanglement concurrence

Quantum entanglement plays a pivotal role in quantum information processing. Quantifying quantum entanglement is a challenging and essential research area within the field. This manuscript explores the relationships between bipartite entanglement concurrence, multipartite entanglement concurrence, and genuine multipartite entanglement (GME) concurrence. We derive lower bounds on GME concurrence from these relationships, demonstrating their superiority over existing results through rigorous proofs and numerical examples. Additionally, we investigate the connections between GME concurrence and other entanglement measures, such as tangle and global negativity, in multipartite quantum systems.
