AbstractQuantum information science and engineering are expanding and scaling worldwide. As government and industry push to expand quantum applications around the world, education institutions scramble to train the next generation of quantum-aware engineers in the Quantum pipeline. However, as educational institutions seek to expand the pipeline, not all learners have access to Quantum training or equipment. Quantum laboratories, an expensive component of STEM education, often remain exclusively accessible to institutions with affluence and funding, thus creating systemic barriers for underrepresented learners to the Quantum pipeline. This design-based case study describes the three-year design and development of a hybrid remote online Quantum laboratory in partnership with historically black colleges and universities across the US with the goal of expanding access for underrepresented learners to Quantum training. The study describes the prototypical design, development, and formative evaluation of the prototype’s iterations and reflects on design decisions made resulting from formative feedback during the design process.
