Query: Quantum Measurement, Complexity and Discrete Physics   This paper presents a new modified quantum mechanics, Critical Complexity
Quantum Mechanics, which includes a new account of wavefunction collapse. This
modified quantum mechanics is shown to arise naturally from a fully discrete
physics, where all physical quantities are discrete rather than continuous. I
compare this theory with the spontaneous collapse theories of Ghirardi, Rimini,
Weber and Pearle and discuss some implications of the theory for a realist view
of the quantum realm.
