论文摘要
我们对经典和量子物理学的等价原理的各种口味进行了一般概述，并特别强调了所谓的弱等价原理，并将其在力学与现场理论中的有效性对比。我们还讨论了其对量子重力理论的概括。我们的分析表明，只有强大的对等原理才能被认为是基本的，以便将其推广到量子重力上下文，因为所有其他等效原理的所有其他口味仅在经典级别上大约已经存在。
We give a general overview of various flavors of the equivalence principle in classical and quantum physics, with special emphasis on the so-called weak equivalence principle, and contrast its validity in mechanics versus field theory. We also discuss its generalisation to a theory of quantum gravity. Our analysis suggests that only the strong equivalence principle can be considered fundamental enough to be generalised to a quantum gravity context, since all other flavors of equivalence principle hold only approximately already at the classical level.
