13Why protective measurement implies the reality of the wave function: further consolidationIn Diederik Aerts, Dalla Chiara, Maria Luisa, Christian de Ronde & Decio Krause (eds.), Probing the meaning of quantum mechanics: information, contextuality, relationalism and entanglement: Proceedings of the II International Workshop on Quantum Mechanics and Quantum Information: Physical, Philosophical and Logical Approaches, CLEA, Brussels, World Scientific. 2019.The existing psi-ontology theorems are based on a simplified assumption of the ontological models framework, according to which when a measurement is performed the behaviour of the measuring device is determined by the ontic state of the measured system immediately before the measurement. In this paper, I give an argument for the reality of the wave function in terms of protective measurements under a more reasonable assumption, according to which the behaviour of the measuring device during a m…Read more

12In collapse theories of quantum mechanics, there exist quantum observers who are observers being in a superposition of different result branches. In this paper, I analyze the mental state of a quantum observer. First, I argue that the mental state of a quantum observer is not the usual state of recording one of the results in the superposition, but it is definite. Second, I argue that the mental state of a quantum observer is determined by both the amplitudes and relative phases of the result br…Read more

12There are three possible interpretations of the wave function in the de Broglie-Bohm theory: taking the wave function as corresponding to a physical entity or a property of the Bohmian particles or a law. In this paper, we argue that the first interpretation is favored by an analysis of protective measurements.

10The free Schrödinger equation is shown to be a consequence of spacetime homogeneity in the non-relativistic domain. This may help understand the origin of the wave equations in quantum theory.

10Psychophysical supervenience requires that the mental properties of a system cannot change without the change of its physical properties. In this paper, I argue that the Everett interpretation of quantum mechanics or Everett's theory seems to violate the principle of psychophysical supervenience. In order to be consistent with our experience, the theory assumes psychophysical supervenience in each world, including our world. However, this permits the possibility that under certain unitary time e…Read more
