论量子态的实在性

On the reality of the quantum state

Matthew F. Pusey, Jonathan Barrett, Terry Rudolph

摘要:

量子态是量子理论的核心数学对象。因此,物理学家无法就量子态真正代表什么达成一致,这是令人惊讶的。一种可能性是纯量子态直接对应于现实。然而,有一个很长的历史的建议,一个量子态(即使是一个纯粹的状态)只代表知识或信息的某些方面的现实。在这里,我们表明,任何一个模型,其中一个量子态代表的仅仅是一个潜在的物理状态的系统的信息,并在其中独立准备的系统有独立的物理状态,必须作出预测,这些与量子理论。

英文摘要:

Quantum states are the key mathematical objects in quantum theory. It is therefore surprising that physicists have been unable to agree on what a quantum state truly represents. One possibility is that a pure quantum state corresponds directly to reality. However, there is a long history of suggestions that a quantum state (even a pure state) represents only knowledge or information about some aspect of reality. Here we show that any model in which a quantum state represents mere information about an underlying physical state of the system, and in which systems that are prepared independently have independent physical states, must make predictions which contradict those of quantum theory.
