Summary

Dr Sarah Kaiser presents an introduction to Q#, Microsoft’s quantum programming language, as part of the UTS Quantum Software and Information seminar series. She begins by discussing the landscape of quantum software tools and the need for a high-level language that abstracts hardware details. She explains the structure of Q# programs, including functions and operations, and demonstrates basic examples such as a quantum random number generator and a multi-controlled X gate. She highlights the use of functors (adjoint and controlled) to generate new operations, and shows how to run Q# programs in Jupyter notebooks, from the command line, or via Python. She also covers the Quantum Development Kit’s target machines, including simulators and resource estimators, and emphasizes the importance of unit testing in quantum research. As a case study, she describes her work on qRAM (quantum random access memory) with collaborators, where they implemented various proposals from the literature in Q# and used resource estimation to compare them. She concludes by sharing open-source resources and community groups, such as the Q# Community and Women in Quantum Computing & Applications, and encourages researchers to adopt open and reproducible practices.
