论文摘要
量子状态的非古老性是量子技术和量子信息任务的基本资源。特别是，量子状态的关键方面在于它们的连贯性能，在Fock-State Bosonic的基础上以其密度矩阵的非对角术语进行编码。我们提出了操作标准，以检测仅在实验现实的场景中使用数据的单个量子相干的非经典性。我们分析和比较当国家通过有损和嘈杂的通道时，非经典相干性方面的鲁棒性。该标准可以立即应用于光，原子，固态系统和机械振荡器的实验，从而提供一个工具箱，从而使实用实验更容易地检测到生成状态的非经典性。
The nonclassicality of quantum states is a fundamental resource for quantum technologies and quantum information tasks in general. In particular, a pivotal aspect of quantum states lies in their coherence properties, encoded in the nondiagonal terms of their density matrix in the Fock-state bosonic basis. We present operational criteria to detect the nonclassicality of individual quantum coherences that only use data obtainable in experimentally realistic scenarios. We analyze and compare the robustness of the nonclassical coherence aspects when the states pass through lossy and noisy channels. The criteria can be immediately applied to experiments with light, atoms, solid-state systems, and mechanical oscillators, thus providing a toolbox allowing practical experiments to more easily detect the nonclassicality of generated states.
