About this project Quantum technologies are developing at breakneck speed, yet understanding how quantum computers actually work remains out of reach beyond a small number of specialists. The very mathematical nature of quantum computing makes it difficult to convey precisely where it gains its advantage over conventional technologies. Metaphors to illustrate quantum superposition abound, but researchers and the popular science media alike are at a loss when it comes to explaining how simple protocols and algorithms work, and what precisely confers them an advantage over classical computing. The goal of this project is to design and construct playful physical devices that model the basic constructs of quantum computation: qubits, superposition. Using this representation, we explain precisely how simple quantum protocols and algorithms work. A digital interface will simulate these objects and make it possible to visualize and experiment with quantum circuits and algorithms. The devices allow us to deploy various learning opportunities, going from workshops with the general public, internal seminars and team-building activities for large businesses and quantum start-ups, as well as undergraduate and Master’s level courses and academic lectures.
