Foundations of Quantum Theory  

General Issues > s.a. [quantum mechanics]; information; interpretations; realism; sub-quantum theories.
* Idea: There are several big conceptual issues in quantum mechanics, related to each other, such as Does a quantum state represent reality or our knowledge of reality? Quantum mechanics has holistic aspects that we have a difficult time understanding.
* History: The intuitive, local realism view of physics was challenged by the EPR "paradox" (1935) about reality, locality and completeness, Bell's inequality (1964) about reality and locality, the Hardy-Jordan experiment (1993) tested by Torgerson et al [@ PLA(95), PLA(96)], GHZ states of N > 2 particles.
* Status: Quantum mechanics has passed all experimental tests so far, many more than it had originally been designed to pass, from the structure of matter to the dynamics of stars and the quantum Hall effect; The problems lie in the interpretational aspects.

Individual Particle or System > s.a. mixed states.
* Wave functions are real: Schrödinger's original interpretation; The wave function is actual density of stuff.
* Problems with wave function = particle: Wave packets spread, particles don't; What about systems with N > 1 particles?
