论文摘要
量子资源理论为广泛研究量子物理现象提供了一个多样化和强大的框架。量子相干性是一种量子资源，是许多量子信息任务中的基本成分。它是对量子信息的广泛兴趣和当前兴趣的主题，自成立以来，已经引入和概括了许多新概念。在这里，我们证明可以通过块不一致的操作将块相干性转化为纠缠。此外，我们发现，通过Naimark扩展，基于POVM的连贯性与块连贯性相关联，从产生纠缠的角度起到了潜在的资源。最后，我们讨论了建立基于POVM的连贯性，需要嵌入渠道和辅助系统的策略，提供一些例子并概括它们的途径。
Quantum resource theories provide a diverse and powerful framework for extensively studying the phenomena in quantum physics. Quantum coherence, a quantum resource, is the basic ingredient in many quantum information tasks. It is a subject of broad and current interest in quantum information, and many new concepts have been introduced and generalized since its establishment. Here we show that the block coherence can be transformed into entanglement via a block incoherent operation. Moreover, we find that the POVM-based coherence associated with block coherence through the Naimark extension acts as a potential resource from the perspective of generating entanglement. Finally, we discuss avenues of creating entanglement from POVM-based coherence, present strategies that require embedding channels and auxiliary systems, give some examples, and generalize them.
