This course will explain why textbook quantum “theory” is merely a mathematical recipe rather than a proper physical theory. It will then cover the most serious obstacles to fixing this problem and to providing a clear metaphysics underpinning the mathematics of quantum theory. We will focus on key no-go theorems (e.g., Bell’s theorem, contextuality theorems, and Extended Wigner’s friend arguments), as well as on key frameworks (e.g., generalized probabilistic theories and ontological models).
