标题： An exploration of the limits of control using quantum superpositions

摘要： 非正交态之间的量子干涉是对由这两个态所代表的非对易物理性质的联合实现的最佳近似。 正如我最近所展示的，这种干涉可以用来证明在小作用量极限下，量子物理偏离了经典因果性。 在这里，我指出这个证明构成了最小作用量原理的失败，并考虑其对我们理解基本物理学的可能影响。 显示英文摘要

摘要： Quantum interferences between non-orthogonal states are the best approximation of a joint realization of the non-commuting physical properties represented by the two states. As I have shown recently, such interferences can be used to demonstrate that quantum physics deviates from classical causality in the limit of small action. Here, I point out that this proof constitutes a failure of the principle of least action and consider possible implications for our understanding of fundamental physics.
