# An Argument Against the Realistic Interpretation of the Wave Function

@article{Rovelli2015AnAA, title={An Argument Against the Realistic Interpretation of the Wave Function}, author={Carlo Rovelli}, journal={Foundations of Physics}, year={2015}, volume={46}, pages={1229-1237} }

Testable predictions of quantum mechanics are invariant under time reversal. But the evolution of the quantum state in time is not so, neither in the collapse nor in the no-collapse interpretations of the theory. This is a fact that challenges any realistic interpretation of the quantum state. On the other hand, this fact raises no difficulty if we interpret the quantum state as a mere calculation device, bookkeeping past real quantum events.

The operational formulations of quantum theory are drastically time oriented. However, to the best of our knowledge, microscopic physics is time-symmetric. We address this tension by showing that the…

The Relational Interpretation of Quantum Physics

The relational interpretation (or RQM, for Relational Quantum Mechanics) solves the measurement problem by considering an ontology of sparse relative events, or facts. Events are realized in…

It is often stated that quantum theory yields probabilities for outcomes of $future$ measurements. This language reinforces a common misconception: that quantum dynamics is time oriented. In fact,…

Quantum causality determines the arrow of time

In the philosophy of science, the origin of an arrow of time is viewed as problematic. We describe here how this arrow really follows from the causal structure of quantum physics. This connection is…

Relational EPR

- Physics
- 2006

It is argued that these EPR-type correlations do not entail any form of “non-locality”, when viewed in the context of this interpretation of quantum mechanics, and the abandonment of strict Einstein realism implied by the relational stance permits to reconcile quantum mechanics.
