Notes on "Why Physics Needs Quantum Foundations" by Lucien Hardy and Robert Spekkens
Link to article
H and S ask: what does quantum theory say about the nature of reality?
The field of Quantum Foundations attempts to answer this question: what does quantum theory say abou tthe nature of reality; what are the principles that underlie quantum theory; why do we have a quantum world and not a classical world or something else?
H and S believe that quantum physics has to go beyond finding solutions to problems and look at the world itself from a quantum perspective (they call this realism).
Quantum Information Science is a combination of computer and information theorists and physicists looking at the foundations of quantum theory.
