Undergrad Decoherence references and a question about the measurement problem

Click For Summary
The discussion centers on the best resources for understanding decoherence, emphasizing both intuitive and mathematical perspectives. Schlosshauer's book is considered a standard reference for the quantum-to-classical transition, while "The Theory of Open Quantum Systems" by Breuer and Petruccione is recommended for a more comprehensive understanding of decoherence's measurable consequences. Additionally, the conversation touches on the idea of quantized probabilities in quantum mechanics and whether this could resolve the measurement problem, though it notes the lack of a coherent model to support this concept. Overall, the participants agree on the significance of these resources in studying decoherence and its implications in quantum mechanics. The exploration of decoherence remains crucial for addressing foundational questions in quantum theory.

TL;DR
Questions on decoherence: references and a
Couple questions here.

1. What do you think is the best source to read about decoherence, both from an intuitive/high level pov, but also with mathematical details. I'd partially read a recommended paper by Schlosshauer a while back, is that still the bible for this?

2. If probabilities in quantum mechanics were themselves quantized (i.e. probabilities couldn't be any real number in [0,1] but had to be an integral multiple a some small number ##\epsilon##), would decoherence then solve the measurement problem? E.g. while interacting with "environments" potential measurement results would eventually have a probability below ##\epsilon## and hence vanish completely. All the probability would shift the single result measured. (Admittedly not sure if this makes sense--I either never got a good grasp of decoherence or I forgot it if I did.)

I'm not sure anyone has ever proposed a coherent model with this property. So I don't know that questions about it are actually answerable since we don't have a model to use to answer them.

Could this book be best suited for your needs?

Now the bible is his book that @StevieTNZ linked above.

I've seen it in the many world context, as a technicality that helps to derive the Born rule.

I think Schlosshauer's book is still the standard reference if one wants to learn about how decoherence is related to the quantum-to-classical transition.

Decoherence itself, however, is primarily a physical process in open quantum systems which has measureable consequences. Schlosshauer is only scratching the surface of this. A more comprehensive reference here is "The Theory of Open Quantum Systems" by Breuer and Petruccione.

I would put it this way: Schlosshauer is mainly for foundations, Breuer and Petruccione is mainly for applications.
