论文摘要
在任何自然科学中,测量是理论与可观察到的现实之间的基本联系。是否可以通过对探测系统的作用的测量获得准确且相关的信息?换句话说,是否可以说服一个关于自然的知识,而又不详细了解信息的获取方式?在本文中,我们表明答案令人惊讶,是的。我们构建并实验实现了量子光学探测测量值,其中探针上的测量值(光子的极化状态)用于提取有关系统的信息,即同一光子的频谱。与先前存在的探测协议不同,我们的测量不需要对探针与系统之间的相互作用的任何了解。
In any natural science, measurements are the essential link between theory and observable reality. Is it possible to obtain accurate and relevant information via measurement whose action on the probed system is unknown? In other words, can one be convinced to know something about the nature without knowing in detail how the information was obtained? In this paper, we show that the answer is surprisingly, yes. We construct and experimentally implement a quantum optical probing measurement where measurements on the probes, the photons' polarization states, are used to extract information on the systems, the frequency spectra of the same photons. Unlike the pre-existing probing protocols, our measurement does not require any knowledge of the interaction between the probe and the system.
