The Rise of Quantum Computing: Technological Applications, Ethical Challenges, and Prospects for the Extended Mind Thesis

In Section “Introduction” we introduce the concept of quantum computing [QC]; in essence, the attempt to solve very complex computational problems characterized by numerous variables interacting simultaneously by using quantum mechanical effects (such as superposition and quantum interference). In Section “Applications of QC”, we summarise some applications of QC developed to date and discuss some of the benefits that this technology may bring about for individuals and society. In Section “Ethical Issues underlying QC”, we evaluate some of the downsides (or ethical challenges) arising from the possible wide-scale implementation of this technology. We claim that QC poses utterly new ethical challenges that will likely require novel conceptual tools and methods to be fully and properly tackled. However, we note that QC is not only crucial for the challenges it poses to ethics but also because it affords unique opportunities for enhancing our cognitive abilities and therefore for improving our cognitive profiles. Thus, in Section “QC and the Extended Mind Thesis”, we explore possible points of contact between QC and the extended mind thesis [EMT]. We argue that QC can provide solid evidence to validate some of the claims underlying EMT. Finally, we wrap up the paper (Section “Conclusion”) by summarising what we have achieved and by pointing out possible future research directions.
