论文摘要
我们使用广义的非上下文性不平等和基础独立的连贯见证人分析了干扰现象中的非经典资源。我们使用最近提出的不平等现象，在同一框架内见证了这两个资源。考虑到以前的上下文优势结果，我们还建议采用这些工具来表征量子信息协议中连贯性和上下文性提供的优势的系统方法。我们实例化了这种方法来实现量子审讯的任务，这是由范式炸弹测试的干涉实验引入的，显示了这种任务的上下文量子优势。
We analyse nonclassical resources in interference phenomena using generalized noncontextuality inequalities and basis-independent coherence witnesses. We use recently proposed inequalities that witness both resources within the same framework. We also propose, in view of previous contextual advantage results, a systematic way of applying these tools to characterize advantage provided by coherence and contextuality in quantum information protocols. We instantiate this methodology for the task of quantum interrogation, famously introduced by the paradigmatic bomb-testing interferometric experiment, showing contextual quantum advantage for such a task.
