Abstract:
In quantum foundations, there is growing interest in the program of reconstructing the quantum formalism from clear physical principles. These reconstructions are formulated in an operational framework, deriving the formalism from information-theoretic principles. It has been recognized that this project is in tension with standard ψ-ontic interpretations. This paper presupposes that the quantum reconstruction program (QRP) (i) is a worthwhile project and (ii) puts pressure on ψ-ontic interpretations. Where does this leave us? Prima facie, it seems that ψ-epistemic interpretations perfectly fit the spirit of information-based reconstructions. However, ψ-epistemic interpretations, understood as saying that the wave functions represents one\'s knowledge about a physical system, recently have been challenged on technical and conceptual grounds. More importantly, for some researchers working on reconstructions, the lesson of successful reconstructions is that the wave function does not represent objective facts about the world. Since knowledge is a factive concept, this speaks against epistemic interpretations. In this paper, I discuss whether ψ-doxastic interpretations constitute a reasonable alternative. My thesis is that if we want to engage QRP with ψ-doxastic interpretations, then we should aim at a reconstruction that is spelled out in non-factive experiential terms.
摘要:
在量子基础中,人们对从清晰的物理原理中重建量子形式主义的计划越来越感兴趣。这些重建是在一个操作框架中制定的,从信息论原理推导形式主义。已经认识到,该项目与标准的Φ-ontic解释处于紧张状态。本文假定量子重建程序(QRP)(i)是一个有价值的项目,并且(ii)对Φ-ontic解释施加压力。这让我们在哪里?初步看来,这似乎完全符合以信息为基础的重建精神。然而,Φ-认识论解释,理解为波函数代表一个人对物理系统的知识,最近在技术和概念上受到了挑战。更重要的是,对于一些从事重建工作的研究人员来说,成功重建的教训是,波函数并不代表世界的客观事实。因为知识是一个积极的概念,这与认识论解释背道而驰。在本文中,我讨论了Φ-doxastic解释是否构成合理的替代方案。我的论文是,如果我们想让QRP与Φ-doxastic解释,那么我们应该着眼于以非事实经验术语阐明的重建。
