Philosophie der Quantenmechanik

Wigner's-friend experiments exploit the fact that quantum theory comprises two different dynamics: the collapse of the wave function and unitary evolution. New proposals involving Wigner's friend experiments have sparked renewed debate in the quantum-foundations community.

A formal method of discerning quantum particles consistent with the symmetrization postulate. In the case of fermions the method guarantees absolute discernibility in any state, whereas for bosons the indiscernibility remains for products of identical states.

Concepts from modal logic and dynamic logic can be used to model and interpret quantum behavior. The main thesis: all non-classical properties of quantum systems are explainable in terms of the non-classical flow of quantum information.
