What if the paradoxical nature of quantum theory could find its source in some undecidability analog to that of Godels incompleteness theorem ? This essay aims at arguing for such Godelian hunch via two case studies. Firstly, using a narrative based on the Newcomb problem, the theological motivational origin of quantum contextuality is introduced in order to show how this result might be related to a Liar-like undecidability. A topological generalization of contextuality by Abramsky et al. in which the logical structure of quantum contextuality is compared with Liar cycles is also presented. Secondly, the measurement problem is analyzed as emerging from a logical error. A personal analysis of the related Wigners friend thought experiment and and a recent paradox by Frauchiger and Renner is presented, by introducing the notion of meta-contextuality as a Liar-like feature underlying the neo-Copenhagen interpretations of quantum theory. Finally, this quantum Godelian hunch opens a discussion of the paradoxical nature of quantum physics and the emergence of time itself from self-contradiction.
Quantum weirdness has been in the news recently, thanks to an ingenious new experiment by a team led by Roland Hanson, at the Delft University of Technology. Much of the coverage presents the experiment as good (even conclusive) news for spooky actio
It is argued that the traditional realist methodology of physics, according to which human concepts, laws and theories can grasp the essence of reality, is incompatible with the most fruitful interpretation of quantum formalism. The proof rests on th
In a recent paper, Rovelli responds to our critical assessment of Relational Quantum Mechanics (RQM). His main argument is that our assessment lacks merit, because we fail to understand, or cope with, the premises of his theory; instead, he argues, w
In this letter, we point to three widely accepted challenges that the quantum theory, quantum information, and quantum foundations communities are currently facing: indeterminism, the semantics of conditional probabilities, and the spooky action at a
I give a scientific perspective, with a personal emphasis, on the seminal 1992 paper, The quantum-state diffusion model applied to open systems, by Gisin and Percival.
