多世界量子理论的观测结果

Observational Consequences of Many-Worlds Quantum Theory

Don N. Page

摘要:

与一个经常提出的主张相反,在“单历史”量子理论和“多世界”量子理论之间可能存在观测上的区别(比如宇宙膨胀或宇宙学常数)。当观察者的数量不是唯一的理论预测时,就会出现这种区别。在单历史理论中,每一个历史都是简单地由它的量子力学概率加权的,但是在考虑随机观测的多世界理论中,也应该有由每一个历史中发生的观测的数量或数量加权的。

英文摘要:

Contrary to an oft-made claim, there can be observational distinctions (say for the expansion of the universe or the cosmological constant) between "single-history" quantum theories and "many-worlds" quantum theories. The distinctions occur when the number of observers is not uniquely predicted by the theory. In single-history theories, each history is weighted simply by its quantum-mechanical probability, but in many-worlds theories in which random observations are considered, there should also be the weighting by the numbers or amounts of observations occurring in each history.
