论文摘要
在本文中，我们在中微子振荡中考虑了量子相关性，相干性和纠缠。我们发现$ l_ {1} $ - 作为连贯度量的标准等于测量不同风味模式之间纠缠的三个可能并发的总和，这些模式在论文中由（M. Blasone等，Europhys。Lett。，{\ bf 112}，20007年）。我们的结果表明，中微子振荡中风味的起源与量子相干性相同。此外，在Wave数据包框架中，通过更改波数据包宽度$σ_{x} $来研究$ l_ {1} $ - 标准的变化。正如预期的那样，由于质量本特征的重叠增加，连贯性的数量增加了$σ_{x} $。
In this paper, we consider the quantum correlations, coherence and entanglement, in neutrino oscillation. We find that the $l_{1}$-norm as a coherence measure is equal to sum of the three possible concurrences for measuring the entanglement among different flavor modes which were calculated in the paper by (M. Blasone et al., Europhys. Lett., {\bf 112}, 20007). Our result shows that the origin of the flavor entanglement in neutrino oscillation is the same as that of quantum coherence. Furthermore, in the wave packet framework, the variation of $l_{1}$-norm is investigated by varying the wave packet width $σ_{x}$. As it is expected the amount of coherence increases by $σ_{x}$ due to the increase in the overlapping of the mass eigenstates.
