Phys. Rev. Lett. 70, 2201–2204 (1993)Consistent interpretation of quantum mechanics using quantum trajectoriesReceived 15 December 1992; published in the issue dated 12 April 1993 The probabilistic element of quantum theory can be combined with the unitary time evolution of Schrödinger’s equation in a natural and consistent way using the idea of a quantum trajectory, the quantum analog of the trajectory traced out in phase space as a function of time by a point representing the state of a closed classical system. A family of quantum trajectories can be defined using bases for the quantum Hilbert space at different times chosen so that an appropriate noninterference condition, related to the Gell-Mann and Hartle notion of medium decoherence, is satisfied. The result is a generalization of the consistent histories approach to quantum mechanics. © 1993 The American Physical Society URL:
