Simon Friederich is an Associate Professor of Philosophy of Science at the University of Groningen. His work focuses on quantum foundations and interpretations, and he has written a book about interpretation of quantum mechanics.
In this episode, we discuss:• The three main types of quantum interpretations: anti-realist/Copenhagen, many-worlds/Everett, and Bohmian mechanics• The measurement problem in quantum mechanics• Phase space quantum mechanics and quantization• The Kochen-Specker theorem and its implications• The Q-function (Husimi function) as an alternative to the Wigner function• Temporal bidirectional stochastic dynamics and its relation to Bell's theorem
Key Highlights:• The distinction between formulation and interpretation in quantum mechanics• Einstein's vision of quantum mechanics as similar to classical statistical mechanics• How the Q-function might provide a new perspective on quantum mechanics• The possibility of violating Bell inequalities through backward-in-time nomological probabilistic dependencies without retrocausality
Quotes:• "For some reason, when it comes to quantum mechanics, people immediately assume you have to then each different formulation automatically comes with an interpretation, which isn't really the case."• "I have come to think that actually this is very weirdly argued because you start with assuming that the quantum dynamic variables are not the classical ones, but they are these self adjoint linear operators. And then you ask yourselves, hey, how can I assign sharp values to those things?"
• "If you think of the quantization mapping as a mapping within quantum theory, and not the self adjointly operators represent the classical dynamical variables, then Kochen Specker non contextuality is not a plausible assumption because all the most promising quantization mappings, they don't preserve algebraic relations."
