量子现实

Unsharp Quantum Reality

Paul Busch, Gregg Jaeger

摘要:

正算子(值)测度(POM)允许人们在传统的基于投影值测度(PVM)的可观测性概念之外推广可观测性概念。在这里,我们认为,这种广义的可观察概念实现了不尖锐现实的一致概念,并随之实现了联合属性的充分概念。一个尖锐或不尖锐的属性通过其成为现实或实现特定测量结果的趋势,将其自身表现为尖锐或不尖锐现实的一个元素。一个属性的这种实现趋势或潜力由相关的量子概率来量化。由此产生的概率作为一定程度的现实的单一情况下的解释将被详细解释,它在解决物理世界的量子和经典帐户之间的紧张关系的作用将被阐明。它将表明,潜力可以被视为一个因果机构,在一个明确的方式演变。

英文摘要:

The positive operator (valued) measures (POMs) allow one to generalize the notion of observable beyond the traditional one based on projection valued measures (PVMs). Here, we argue that this generalized conception of observable enables a consistent notion of unsharp reality and with it an adequate concept of joint properties. A sharp or unsharp property manifests itself as an element of sharp or unsharp reality by its tendency to become actual or to actualize a specific measurement outcome. This actualization tendency - or potentiality - of a property is quantified by the associated quantum probability. The resulting single-case interpretation of probability as a degree of reality will be explained in detail and its role in addressing the tensions between quantum and classical accounts of the physical world will be elucidated. It will be shown that potentiality can be viewed as a causal agency that evolves in a well-defined way.
