This research addresses the unique challenges faced by quantum and hybrid quantum-classical (HQC) software developers, focusing on recurring bugs and workflow inefficiencies. Through an empirical analysis of developer forums, a comprehensive taxonomy of issues was developed, categorizing common errors previously largely unidentified in areas such as quantum state manipulation, gate operations, HQC integration and many other areas. Building on these insights, this work proposes the development of specialized tools and methodologies informed by practitioners—such as a static analysis tool and an automated testing framework—to support effective debugging and testing in quantum applications. The ultimate goal is to enhance productivity and reliability in quantum software engineering, contributing to a robust quantum development ecosystem.
