It's not an expression. It's a physical entity. Superposition = information based on preparation. Thus, you have presented us three different preparations, three different physical systems. Surely there must be a way to tell them apart. If those are systems where "internal space/distance" of...

Space in quantum mechanics seems to be modeled as a triplet of real numbers, i.e. a continuum. Same happens in special relativity. General relativity I do not know (nor field theories). And then we apply the Pythagorean theorem and triangle inequality and so forth... I have a few general...

Which mass? Rest mass? Show me a photon at rest :D The concept of mass is a little bit more complicated than "m". And no, I do not fully understand it. Not even nearly so. You may also be interested in: Invariant mass, mass in special relativity, gravitational lens, mass in general relativity, ...

These answers were very helpfull. Thank you. Are there some hidden weaknesses in the axioms of the C*-algebra formulation that have made it unpopular, or is it still considered scientifically as valid as the other formulations?

As far as I understand, the Hilbert space formalism can be derived using functional analysis and representation theory (not familiar with those) from the requirement that observables (their mathematical models) form a C*-algebra and the possible states of a system map the members of the algebra...

What has brought me here? I have read about exciting experimental discoveries that challenge the intuition (e.g. about quantum physics), and I have studied the well defined and beautiful structures of mathematics. What is "slightly" confusing though, is the meeting ground of these. Anyway, both...
