实用主义观点中的量子退相干:I部分

Quantum decoherence in a pragmatist view: Part I

Richard Healey

摘要:

退相干的量子理论在量子理论的实用主义解释中起着重要的作用。它管理着关于物理量值的描述性内容,并提供了何时使用量子概率作为真理指南的建议。权利要求的内容应根据其在推论中的作用来理解。这保证了比玻尔更好地处理意义。量子理论对物理系统进行建模,但没有提到测量:是退相干,而不是测量,允许玻恩概率规则的应用。因此,量子理论也为它自己的应用提供了建议。我展示了这是如何在一个简单的退相干模型,然后在实验室实验和自然系统的应用。应用于量子场论和测量问题将在别处讨论。

英文摘要:

The quantum theory of decoherence plays an important role in a pragmatist interpretation of quantum theory. It governs the descriptive content of claims about values of physical magnitudes and offers advice on when to use quantum probabilities as a guide to their truth. The content of a claim is to be understood in terms of its role in inferences. This promises a better treatment of meaning than that of Bohr. Quantum theory models physical systems with no mention of measurement: it is decoherence, not measurement, that licenses application of Born's probability rule. So quantum theory also offers advice on its own application. I show how this works in a simple model of decoherence, and then in applications to both laboratory experiments and natural systems. Applications to quantum field theory and the measurement problem will be discussed elsewhere.
