摘要
We examine the consequences of the density matrix approach to quantum theory in the context of a model spacetime containing closed timelike curves. We find that, in general, an initially pure state will evolve in a nonlinear way to a mixed quantum state. CPT invariance and the implications of this nonlinearity for the statistical interpretation of quantum theory are discussed.
