为什么是量子?

Why the quantum?

Jeffrey Bub

摘要:

本文是对克利夫顿-布布-哈尔沃森定理的基本意义的评论,该定理用三个信息论约束来表征量子理论(物理学基础33,1561-1591(2003); quant-ph/0211089)。我认为:(1)量子理论最好理解为关于信息传递的可能性和不可能性的理论,而不是关于非经典波或粒子的力学的理论,(2)给定信息理论的约束,任何量子现象的力学理论,包括对揭示这些现象的测量仪器的说明,必须在经验上等价于量子理论,(3)假设信息论的约束在我们的世界中实际上是满足的,那么任何包含测量相互作用的量子现象的力学理论都是不可接受的,那么物理学在基本层面上的适当目标就变成了信息的表示和操纵。

英文摘要:

This paper is a commentary on the foundational significance of the Clifton-Bub-Halvorson theorem characterizing quantum theory in terms of three information-theoretic constraints (Foundations of Physics 33, 1561-1591 (2003); quant-ph/0211089). I argue that: (1) a quantum theory is best understood as a theory about the possibilities and impossibilities of information transfer, as opposed to a theory about the mechanics of nonclassical waves or particles, (2) given the information-theoretic constraints, any mechanical theory of quantum phenomena that includes an account of the measuring instruments that reveal these phenomena must be empirically equivalent to a quantum theory, and (3) assuming the information-theoretic constraints are in fact satisfied in our world, no mechanical theory of quantum phenomena that includes an account of measurement interactions can be acceptable, and the appropriate aim of physics at the fundamental level then becomes the representation and manipulation of information.
