The paper discusses the impacts of Quantum Computer (QC) technology in Industry 5.0 scenarios by focusing attention on application fields such as production management in manufacturing and business modelling. The analysed literature allows for comprehending possible QC implementations and integration in technological architectures. Specifically, the work highlights QC impacts on organization, production and marketing and defines QC perspectives, advantages and possible limitations. The study also addressed the design of workflow modelling production protocols in Industry 5.0 environments implementing QC processes. The analysis of the impacts, together with the technological aspects and the QC process management, are the main topics of the proposed paper. The paper is structured as follows. In section 1, an outline of the main QC applications and potential impacts is provided. Section 2 proposes a framework to explain the role of QC in the technological integration of Industry 5.0 production systems. Section 3 introduces a Business Process Modelling and Notation (BPMN) workflow embedding QC processes and oriented on standardising industrial production protocols. Finally, the conclusion summarizes QC advantages, perspectives and limits matching with the performed analysis.
