Quantum computing code development has been hindered by the limitations of general-purpose proprietary models, but a new reference implementation called QiboAgent offers a solution. This open-source assistant is designed to provide a guideline for practitioners to develop specialized coding assistants in Quantum Computing middleware. By leveraging lightweight, open-source Large Language Models (LLMs) and a custom workflow architecture, QiboAgent addresses the shortcomings of traditional models. The use of LLMs enables more efficient and effective code development, allowing practitioners to focus on complex quantum computing tasks. QiboAgent's open-source nature also promotes collaboration and customization, enabling developers to tailor the assistant to their specific needs. As quantum computing continues to advance and challenge traditional notions of computation and cryptography, the development of specialized tools like QiboAgent is crucial1. This matters to practitioners because it enables them to stay at the forefront of quantum computing innovation and tackle complex problems with greater ease.
