  Knowledge of quantum mechanical systems is becoming more important for many
science and engineering students who are looking to join the emerging quantum
workforce. To better prepare a wide range of students for these careers, we
must seek to develop new tools to enhance our education in quantum topics. We
present initial studies on the use of one of these such tools, Quantum
Composer, a 1D quantum simulation and visualization tool developed for
education and research purposes. In particular, we conducted five think-aloud
interviews with students who worked through an exercise using Quantum Composer
that focused on the statics and dynamics of quantum states in a single harmonic
well system. Our results show that Quantum Composer helps students to obtain
the correct answers to the questions posed, but additional support is needed to
facilitate the development of student reasoning behind these answers. We also
show that students are able to focus only on the relevant features of Quantum
Composer to achieve the task.
