完全真实?对科尔贝克和伦纳主张的批判性说明
Completely real? A critical note on the claims by Colbeck and Renner
摘要:
在一系列论文中,科尔贝克和伦纳声称已经证明了量子态为预测未来的测量结果提供了完整的描述。在本文中,我认为,到目前为止,没有坚实的令人满意的证据已经提出来支持这一主张。早期的工作Leifer,Landsman和Leegwater的基础上,我提出并证明了两个结果,只有部分支持这一说法。然后,我讨论的论点科尔贝克,伦纳和Leegwater关于如何将这些结果推广到充分的索赔。这一论点的关键在于隐含地使用了一个假设,即在量子力学的任何可能的完善中,酉演化都是以某种方式来表示的。我认为,这一假设是不能令人满意的,可能的尝试,以验证它的基础上测量理论也不成功。
英文摘要:
In a series of papers Colbeck and Renner claim to have shown that the quantum state provides a complete description for the prediction of future measurement outcomes. In this paper I argue that thus far no solid satisfactory proof has been presented to support this claim. Building on the earlier work of Leifer, Landsman and Leegwater, I present and prove two results that only partially support this claim. I then discuss the arguments by Colbeck, Renner and Leegwater concerning how these results are to generalize to the full claim. This argument turns out to hinge on the implicit use of an assumption concerning the way unitary evolution is to be represented in any possible completion of quantum mechanics. I argue that this assumption is unsatisfactory and that possible attempts to validate it based on measurement theory also do not succeed.
