论文摘要
经典和量子力学之间的根本差异之一是可以在组成系统的许多当事方之间分布相关性的方式。尽管可以在许多子系统之间共享经典相关性,但总体上不能自由共享量子相关性。这种独特的特性称为量子相关性的一夫一妻制。在这项工作中,我们研究了相干性的相关性和相对熵测量的相关性的一夫性特性。对于L 1纳态,对于特定类别的量子状态,相关的连贯性是一夫一妻。对于连贯性的相对熵,并使用最大混合状态作为参考不一致的状态,我们表明相关的连贯性对于三方纯量子系统是一夫一妻制的。
One of the fundamental differences between classical and quantum mechanics is in the ways correlations can be distributed among the many parties that compose a system. While classical correlations can be shared among many subsystems, in general quantum correlations cannot be freely shared. This unique property is known as monogamy of quantum correlations. In this work, we study the monogamy properties of the correlated coherence for the l 1 -norm and relative entropy measures of coherence. For the l 1 -norm the correlated coherence is monogamous for a particular class of quantum states. For the relative entropy of coherence, and using maximally mixed state as the reference incoherent state, we show that the correlated coherence is monogamous for tripartite pure quantum systems.
