Quantum Quantum Theory from First Principles

[Frabjous]

@LittleSchwinger recently recommended this book

If you enjoy it D'Ariano et al's "Quantum Theory from First Principles" uses a similar diagramatic approach but is more concise and rigorous.

What are peoples thoughts on it?

 

[LittleSchwinger]

I fully agree with my own recommendations

Basically the book is divided into three parts:

1. An examination of the Hilbert space formalism of quantum theory and how it generalises information theory.
2. A discussion of information theoretic principles and how aspects of quantum theory are simply consequences of them
3. A derivation of quantum theory from six information theoretic principles

Note: I say "quantum theory" to refer to the abstract formalism of Hilbert Spaces and operators on them. The book does not examine any physics as such, i.e. explicit systems like hydrogen atoms, harmonic oscillators, gases etc. It's an investigation of the abstract formalism.

The exercises are very well crafted and often take the form of a guided development of ideas from the text.
