Quantum computing is rapidly emerging as a transformative technology with the potential to improve multiple industries and their efficiency. Since quantum algorithms typically rely on a hybrid combination of classical and quantum computing, efficient orchestration mechanisms are critical for effective execution. Traditional workflow languages, such as BPMN (Business Process Model and Notation), are well suited to describe orchestrations since they allow the explicit model of process flows and interactions between systems. Although Business Process Model and Notation (BPMN) and its similar tools may be accepted quite appropriately for modeling workflows in hybrid systems, they lack an innate ability to capture the unique computational features native to quantum systems. Quantum Humanities Analysis Tool (QHAna) is a framework that addresses this specific challenge by offering tools to design and implement hybrid quantum-classical workflows. Researchers can quickly model, execute, and analyze hybrid algorithms using established methodologies such as BPMN. Workflow modeling, a proven approach in traditional computing, offers an excellent framework for managing and modeling complex quantum workflows. However, quantum computing introduces multiple requirements that demand the development of new workflow features. Traditional workflow tools may not address the specific challenges and needs of quantum algorithms. To evaluate the performance of quantum computing and compare it with classical computing, tools such as QHAna can be used. QHAna provides a benchmark that enables its users to assess the advantages and limitations of quantum computing using various tools. One of these tools needed for QHAna is a workflow modeling framework capable of handling quantum components while also handling classical ones. By integrating the workflow modeler into QHAna, users can gain a more significant understanding of the performance of quantum algorithms and identify areas where they can be improved. This thesis builds on and improves the BPMN standard by integrating the Quantum Workflow Modeler into QHAna to simplify the graphical modeling of data flow and transformations. Quantumspecific modeling components can be added to this modeler by extending its already existing plugin-based architecture.
