Query: Interaction-Induced Wave Function Collapse Respects Conservation Laws   Because quantum measurements have probabilistic outcomes they can seem to
violate conservation laws in individual experiments. Despite these appearances,
strict conservation of momentum, orbital angular momentum, and energy can be
shown to be consistent with the assumption that the entangling interactions
that constitute measurements induce a real collapse of the wave function. The
essential idea is that measured systems always have some pre-existing
entanglement relations with (usually larger) systems, and that apparent changes
in conserved quantities in the measured system are correlated with compensating
changes in these larger systems. Since wave function collapse is mediated by
entanglement relations a full accounting of the relevant quantities requires a
computation over all interacting, entangled systems. The demonstrations by
Gemmer and Mahler[1], and by Durt[2,3], that entanglement is a generic result
of interaction are central to the argument. A stochastic collapse equation
based on interaction potentials is described and shown to guarantee
conservation of the relevant quantities at all stages of evolution.
