Is Quantum Mechanics Non-Local?

W.G. Unruh

Dept. of Physics, UBC

Since the Proof of Bell's theorem in the 1960's the impression has grown that it implies that quantum mechanics is a non-local theory, and even people who should know better talk about quantum mechanics as if it is non-local. I will review some of the issues, and try to make as good a case as I can for its non-locality, but ultimately argue that it is a local theory. But along the way many of the most unusual features of quantum mechanics will be reviewed, and some philosophical issues regarding counterfactual reasoning will be discussed.
