An argument against the realistic interpretation of the wave function

Carlo Rovelli Testable predictions of quantum mechanics are invariant under time reversal. But the change of the quantum state in time is not so, neither in the collapse nor in the no-collapse interpretations of the theory. This fact challenges the realistic interpretation of the quantum state. On the other hand, this fact follows easily if we interpret the quantum state... Read more →

Concerning Quadratic Interaction in the Quantum Cheshire Cat Experiment

We believe the weak interaction of the quantum Cheshire Cat experiment must be linear if the weak values are to support the quantum Cheshire Cat interpretation, i.e., that a particle and one of its properties are spatially separated. For example, even though Denkmayr et al. measured the proper weak values for quantum Cheshire Cat in their neutron interferometry experiment, they did so using a quadratic...

In memory of Bernard d’Espagnat (1921-2015)

We am very sorry to hear of the passing of Bernard d’Espagnat, a distinguished member of our Editorial Board. Prof. d'Espagnat died on 1 August 2015, at age 93 in Paris. He has made important contributions to the foundations of quantum mechanics, and is especially famous for his concept of 'veiled reality'. He won the 2009 Templeton Prize. Prof. d'Espagnat had been supporting our journal and the... Read more →
