论文摘要
Leggett-Garg不平等〜（LGI）是贝尔不平等的时间类似物，涉及在不同时间对系统进行的测量。违反LGI表示量子相干。我们提出了与更一般的中微子振荡框架兼容的leggett-garg型不平等，从而可以考虑将逆转性的效果考虑在内。不平等应用于测试来自Daya Bay，MINOS和Kamland实验的数据的连贯性，并将其结果与研究反应性的理论预测进行了比较。 Daya Bay和MINOS数据都明显违反了超过$10σ$的规定，而90美元的理论预测的90美元$ \％$ \％，而Kamland数据的违反了$1.9σ$，理论预测的58美元$ \％$。目前的工作是第一个考虑了中微子相干测试中的能量不确定性。
Leggett-Garg Inequality~(LGI) is a time analogue of Bell's inequality that concerns measurements performed on a system at different times. Violation to LGI indicates quantum coherence. We present a Leggett-Garg-type inequality compatible with more general neutrino oscillation frameworks, allowing the effects of decoherence to be taken into consideration. The inequality is applied to test coherence for data from Daya Bay, MINOS, and KamLAND experiments, and their results are compared to theoretical predictions to investigate decoherence. Both Daya Bay and MINOS data exhibit clear violations of over $10σ$, and of over 90$\%$ of theoretical predictions, while the KamLAND data exhibit violation of $1.9σ$, being of 58$\%$ of the theoretical prediction. The present work is the first to have considered the energy uncertainties in neutrino coherence tests.
