The Future of Quantum Theory: A Way Out of the Impasse

Ghislain Fourny

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 distance. We argue that these issues are fundamentally rooted in conflations commonly made between causal dependencies, counterfactual dependencies, and statistical dependencies. We argue that a simple, albeit somewhat uncomfortable shift of viewpoint leads to a way out of the impossibility to extend the theory beyond indeterminism, and towards the possibility that sound extensions of quantum theory, possibly even deterministic yet not super-deterministic, will emerge in the future. The paradigm shift, which we present here, involves a non-trivial relaxation of the commonly accepted mathematical definition of free choice, leading to non-Nashian free choice, more care with the choice of probabilistic notations, and more rigorous use of vocabulary related to causality, counterfactuals, and correlations, which are three concepts of a fundamentally different nature.

量子理论的未来:走出僵局的出路

在这封信中,我们指出了量子理论、量子信息和量子基础社区目前面临的三个被广泛接受的挑战:不确定性、条件概率的语义和远距离的幽灵行动。我们认为,这些问题的根本根源在于因果依赖、反事实依赖和统计依赖之间常见的混淆。我们认为,一个简单的,尽管有点令人不舒服的观点转变导致了一条出路,无法将理论扩展到非决定论之外,并走向量子理论的合理扩展的可能性,甚至可能是确定性的但不是超确定性的,将出现在未来。我们在这里介绍的范式转变,
