Quantum Software Testing 101

Quantum software testing (QST) is an emerging research area within quantum software engineering (QSE) to ensure quantum software functional and non-functional correctness and dependabil-ity. Since quantum computers perform computations significantly differently than classical computing, testing quantum software run-ning on these quantum computers also differs due to quantum computing's unique characteristics, e.g., entanglement and super-position. Due to the rising interest of the software engineering community in QSE, we will provide an introduction to QST. We will introduce quantum computing and its various principles, quan-tum software development as quantum circuits, and current QST literature, including a key set of techniques with examples. Finally, a set of future research challenges related to QST will be presented.
