In the context of the Italian Quantum Weeks initiative, the exhibition "Dire l'indicibile" proposed a journey through the rules of Quantum Mechanics, offering a glimpse at the working principles and potential applications of quantum technologies (QTs).We devised a route to introduce the key concepts of quantum superposition, quantum measurements and evolution, and incompatible observables, by exploiting analogies based on custom-made models and tools.As examples of possible QT applications, we choose to discuss: i) the peculiarities of quantum walks (QW), as compared to classical random walks; ii) quantum cryptography and its applications.Two activities -illustrating the basis of QWs and of the BB84 quantum key distribution protocol-were actively performed by the public.The outcome of a satisfaction survey is extremely positive, encouraging us to explore this approach in different educational contexts.
