Quantum computing (QC) aims to solve a multitude of complex problems, e.g., in medicine, finance, aerospace, and simulation. Solving such problems requires developing quantum software. Building reliable, correct, and correct quantum software is essential to realize the promised revolutionary QC applications. To this end, the field of quantum software engineering (QSE) is emerging, which covers many aspects such as requirements engineering, modeling, programming, testing and debugging. Each of these aspects is a big research area, and demands investigation of its own. The Q-SANER workshop will in particular focus on the quantum software (including circuits) analysis, evolution, and reengineering aspects of QSE. Moreover, it will also cover other related aspects of quantum software, i.e., software analysis, evolution, and reengineering of quantum software compilers, quantum computer emulators, and quantum software development environments. The key goals of the workshop are: 1) Discussion on how to apply and extend existing approaches in software analysis, evolution and reengineering techniques from the classical domain to quantum software and quantum circuits, or develop entirely new approaches; 2) Facilitate collaboration on quantum software analysis, evolution and reengineering between industry and academia; 3) Discussion on the educational aspects related to quantum software analysis, evolution and reengineering; 4) Discuss the challenges and future research directions; 5) Disseminate the results to practitioners with the aim of influence their current practise.
