On the State of Superposition and the Parallel or not Parallel Nature of Quantum Computing: a controversy raising point of view

摘要

In this paper we use ideas coming from the field of computing to propose a model of quantum systems, which gets rid of the concept of superposition while reproducing the observable behaviour of quantum systems as described by quantum mechanics. On the basis of this model we contest the interpretation of quantum mechanics based on the so-called quantum superposition and the related parallel-computing interpretation of quantum algorithms. The goal of this presentation is to bring for discussion in the conference ontological arguments against the so-called quantum parallelism, which are mutually supported with recent advances in complexity analysis of quantum algorithms.
