# Some Worlds of Quantum Theory

@article{Butterfield2001SomeWO, title={Some Worlds of Quantum Theory}, author={Jeremy Butterfield}, journal={arXiv: Quantum Physics}, year={2001} }

Abstract: This paper assesses the Everettian approach to the measurement problem, especially the version of that approach advocated by Simon Saunders and David Wallace. I emphasise conceptual, indeed metaphysical, aspects rather than technical ones; but I include an introductory exposition of decoherence. In particular, I discuss whether---as these authors maintain---it is acceptable to have no precise definition of 'branch' (in the Everettian kind of sense). (A version of this paper will…
