  We summarize a new realist interpretation of quantum theory that builds on
the existing physical structure of the theory and allows experiments to have
definite outcomes, but leaves the theory's basic dynamical content essentially
intact. Much as classical systems have specific states that evolve along
definite trajectories through configuration spaces, the traditional formulation
of quantum theory asserts that closed quantum systems have specific states that
evolve unitarily along definite trajectories through Hilbert spaces, and our
interpretation extends this intuitive picture of states and Hilbert-space
trajectories to the case of open quantum systems as well. Our
interpretation---which we claim is ultimately compatible with Lorentz
invariance---reformulates wave-function collapse in terms of an underlying
interpolating dynamics, makes it possible to derive the Born rule from deeper
principles, and resolves several open questions regarding ontological stability
and dynamics.
