Abstract
In this paper, we introduce Qsyn, a novel quantum circuit synthesis (QCS) framework designed to facilitate the research, development, testing, and experimentation of QCS algorithms and tools. Our framework is more developer-friendly than other modern QCS frameworks in three aspects: (1) Qsyn provides a comprehensive command-line interface that enables developers to design various testing scenarios with ease and conduct flexible experiments on their algorithms. This feature significantly streamlines the development process, making it more efficient and user-friendly. (2) Qsyn offers detailed access to multiple data representations at different abstraction levels of quantum circuits. This capability allows developers to optimize their algorithms extensively, gaining deeper insights and control over the structure and behavior of quantum circuits. By understanding the intricacies of circuit design, developers can achieve higher levels of optimization and performance in their algorithms. (3) Qsyn implements a rigorous development flow and environment to help developers maintain high-quality standards using modern software engineering practices, including robust quality assurance measures like regression testing, continuous integration and continuous delivery (CI/CD) pipelines, and code linting. We demonstrate Qsyn's superior performance through fair comparisons with PyZX [1], highlighting its efficiency and optimization capabilities. By providing a unified and user-friendly development environment, Qsyn empowers researchers and developers to prototype, implement, and evaluate their QCS algorithms effectively.
