A Causal-Modelling Reconstruction of Quantum Mechanics That Comes With its Own Interpretation — •Joppe Widstam — Max Planck Institute for the Physics of Complex Systems, Dresden, Germany

We reconstruct quantum mechanics from intuitive causal-modelling principles for time-symmetric physics. In this reconstruction, the quantum state is a mere convenient mathematical object for agents able to control the initial conditions and who are able to choose what observable to measure.
