      Quantum technologies refer to any technology developed based on the principles of quantum physics. Quantum communication, quantum computing, and quantum sensing are applications of such technologies, in which quantum mechanics underpins the key assumptions on their design and development. Quantum technologies promise revolutionary and disruptive innovations across a wide range of industries. Quantum computing will play an important role in artificial intelligence and will have an impact on every sector of the economy, from healthcare to national security. Currently, the workforce possessing a fundamental understanding of, and the technical skills needed for, quantum technologies is limited. This situation creates a significant challenge for educational system to address. There is a need to attract young people from diverse backgrounds to become engineers and scientists trained in quantum technologies. However, teaching a counterintuitive concept such as quantum cryptography might confuse young learners. Quantum cryptography is disconnected from physical realities that students expect to observe. Due to its nontrivial and counterintuitive aspects, it should be taught based on conceptual ideas rather than complex mathematical formulizations (Krijtenburg-Lewerissa, Brinkman, and van Joolingen, 2017). In this article, the authors demonstrate how to conduct an experiment with a quantum cryptography demonstration kit (Thorlabs 2017) and then provide a sample lesson plan about quantum key distribution (QKD), which illustrates the distribution of a key (or password) to encrypt or decrypt messages with the use of quantum properties based on the BB84 protocol developed by Bennett and Brassard (1984; 2014).
