  Refactoring is a crucial technique for improving the efficiency and
maintainability of software by restructuring its internal design while
preserving its external behavior. While classical programs have benefited from
various refactoring methods, the field of quantum programming lacks dedicated
refactoring techniques. The distinct properties of quantum computing, such as
quantum superposition, entanglement, and the no-cloning principle, necessitate
specialized refactoring techniques. This paper bridges this gap by presenting a
comprehensive set of refactorings specifically designed for quantum programs.
Each refactoring is carefully designed and explained to ensure the effective
restructuring of quantum programs. Additionally, we highlight the importance of
tool support in automating the refactoring process for quantum programs.
Although our study focuses on the quantum programming language Q\#, our
approach is applicable to other quantum programming languages, offering a
general solution for enhancing the maintainability and efficiency of quantum
software.
