Gotta put in a plug for QIT, which is very similar, but I think a little easier to understand: https://arxiv.org/abs/quant-ph/9512022 and a more accessible version that I wrote a long time ago: https://flownet.com/ron/QM.pdf

> Even for isolated systems where, in principle, we could have zero surprisal and access to all possible information... This makes no sense. How could you have access to "all possible information" in an isolated system? You obviously can't make any measurements, and if the system is prepared, then it's entangled with the system used to prepare it and again cannot be isolated. The whole notion of "an isolated system" is a theoretical fiction that doesn't actually exist in physical reality, but even in theory one cannot access all of the information in an isolated system because of the…
