Philosophy of Physics Seminar (Thursday - Week 2, MT20)

One of our most sophisticated accounts of objective chance in quantum theories involves the Deutsch-Wallace theorem, which uses symmetries of the quantum state space to justify agents’ use of the Born rule when the quantum state is known. But Wallace (2003, 2012) argues that this theorem requires an Everettian approach to measurement. I find this argument to be unsound, and I demonstrate a counter-example by applying the Deutsch-Wallace theorem to Bohmian mechanics.

The Seminar will take place via Microsoft Teams. Please email James Read if you would like to attend.
