Sorkin has introduced a new, observer independent, interpretation of quantum mechanics that can give a successful realist account of the 'quantum microworld' as well as explaining how classicality emerges at the level of observable events for a range of systems including single time 'Copenhagen measurements'. This 'co-event interpretation' presents us with a new ontology, in which a single 'co-event' is real. A new ontology necessitates a review of the dynamical & predictive mechanism of a theory, and in this paper we begin the process by exploring means of expressing the dynamical and predictive content of histories theories in terms of co-events.
Quantum probabilities: an information-theoretic interpretation
本章将对量子概率的非经典特征进行实在论的信息论解释。按照这种观点，从经典物理学到量子物理学的过渡中最根本的是认识到，正如从经典物理学到相对论物理学的过渡依赖于认识到时空在结构上与我们想象的不同一样，\emph{information in the physical sense has new structural features}也是如此。希尔伯特空间，量子系统的事件空间，被解释为运动学（即，希尔伯特空间的几何结构对事件之间的相关性施加了客观的概率或信息论约束，就像狭义相对论中闵可夫斯基空间的几何结构对事件施加了时空运动学约束一样。量子概率的解释在精神上比本书中的其他讨论更主观（eidogg.，Timpson的那一章），就量子态被解释为一种信任函数--一种记录概率的簿记设备--而言，但它也是客观的（或主体间性），只要由量子态指定的信任被理解为唯一确定的，通过格里森定理，由希尔伯特空间的子空间结构定义的非经典量子事件空间中事件的客观相关约束。
