Dynamical quantum jumps were initially conceived by Bohr as objective events associated with the emission of a light quantum by an atom. Since the early 1990s they have come to be understood as being associated rather with the detection of a photon by a measurement device, and that different detection schemes result in different types of jumps (or diffusion). Here we propose experimental tests to rigorously prove the detector dependence of the stochastic evolution of an individual atom. The tests involve no special preparation of the atom or field, and the required efficiency can be as low as η≈58%.
动态量子跃迁最初是由玻尔设想的，它们是与原子发射光量子相关的客观事件。自 20 世纪 90 年代初以来，人们逐渐认识到它们与测量设备检测光子有关，并且不同的检测方案会导致不同类型的跃迁（或扩散）。在这里，我们提出了实验测试来严格证明单个原子的随机演化对探测器的依赖性。这些测试不需要对原子或场进行特殊准备，所需的效率可以低至 η≈58%。
