Part of the Lecture Notes in Physics book series (LNP, volume 517)


The quantum trajectory theory of photon scattering in quantum optics is reviewed. Two features of the theory which bear closely on issues of interpretation in quantum mechanics are emphasized: (1) there exist different unravellings of a scattering process which reveal complementary aspects of the dynamics in the interaction region, and (2) through the making of records via a stochastic implementation of a formalized quantum jump a self-consistent interface between a quantum evolution (in Hilbert space) and a classical evolution for the records (time series of real numbers) is achieved.
