Quantum information theory is the way many professors of quantum mechanics understand the topic these days. The language reflects a shift towards the point you are making CH. The math is the same, but now there is someone who wants to know added to the picture asking questions with a cognitive abstraction added that reflects the reality of the observer. This is the natural progression as quantum systems become tools for computation and storage of data. What that information is is in the eye of the beholder.
I totally agree
