我们提出了一种基于能量因果集的量子理论方法，在[M。科尔特斯和L. Smolin，arXiv：1307.6167].基本过程是事件携带动量和能量的因果集合，这些动量和能量在每个事件中沿着因果联系传递并保持不变。从根本上说，这种因果过程有振幅，但没有时空。因果过程在突现时空中的嵌入只在半经典层次上出现。因此，根本上不存在对易关系，不存在测不准原理，实际上也不存在h。量子理论所剩下的就是复振幅的绝对值平方和概率之间的关系。因此，我们发现，无论是局部性或非局部性是一个主要的概念，只有因果关系存在于基本水平。
We propose an approach to quantum theory based on the energetic causal sets, introduced in [M. Cortes and L. Smolin, arXiv:1307.6167]. Fundamental processes are causal sets for which the events carry momentum and energy, which are transmitted along causal links and conserved at each event. Fundamentally there are amplitudes for such causal processes, but no space-time. An embedding of the causal processes in an emergent space-time arises only at the semiclassical level. Hence, fundamentally there are no commutation relations, no uncertainty principle and, indeed, no h. All that remains of quantum theory is the relationship between the absolute value squared of complex amplitudes and probabilities. Consequently, we find that neither locality nor nonlocality is a primary concept; only causality exists at the fundamental level.
