从协变性概率?
Probabilities from envariance?
摘要:
祖雷克声称,他在对量子态的本体论非坍缩解释的背景下,非循环地推导出了玻恩定则,而没有任何“机械的上帝强加的经典性症状”。“在简要回顾了Zurek的推导之后,有人认为这种说法即使不是完全不合理,也是夸大了。为了证明玻恩定则是从确定性演化的量子态中非循环地产生的,假设量子态以某种方式与概率相关联,然后证明这些概率是由玻恩定则给出的是不够的。我们必须证明,在量子态的本体论不坍缩解释的背景下,不可约概率是如何产生的。有人认为,迄今为止所有尝试都失败的原因是,量子态从根本上说是计算可能的测量结果之间的相关性的算法,而不是进化的本体论状态。
英文摘要:
Zurek claims to have derived Born's rule noncircularly in the context of an ontological no-collapse interpretation of quantum states, without any "deus ex machina imposition of the symptoms of classicality." After a brief review of Zurek's derivation it is argued that this claim is exaggerated if not wholly unjustified. In order to demonstrate that Born's rule arises noncircularly from deterministically evolving quantum states, it is not sufficient to assume that quantum states are somehow associated with probabilities and then prove that these probabilities are given by Born's rule. One has to show how irreducible probabilities can arise in the context of an ontological no-collapse interpretation of quantum states. It is argued that the reason why all attempts to do this have so far failed is that quantum states are fundamentally algorithms for computing correlations between possible measurement outcomes, rather than evolving ontological states.
