Many of the differences between the quantum and classical worlds are most visible when studying measurements. For example, classical measurements are repeatable and their outcomes are objective, whereas only measurements of quantum systems which exhibit quantum Darwinism have these properties and so support the emergence of classicality. Another difference is that the outcomes of sets of classical measurements can always be described with joint probability distributions, whereas sets of quantum measurements may require quasiprobabilities.
