A comparison between the First and the Second Quantum Revolutions: Development of a teaching course for secondary school students

We are now experiencing the Second Quantum Revolution. It follows a first one that took place at the beginning of the XX Century and from which the fundamental idea of wave-particle duality was born. During the last century, this revolution led to the development of some technologies at the base of modern society like transistors and lasers. The Second Quantum Revolution is giving rise to new kinds of technologies such as quantum sensors, quantum communication protocols, quantum computers and quantum simulators. It is changing the world we live in and, as educators, we are called to promote quantum literacy and contribute to preparing the next generations of experts. In the present contribution, we present a teaching module on these themes targeted at high school students that aims to introduce some basic concepts and ideas to grasp what quantum technologies are, as well as foster a reflection on the cultural and conceptual scope of the ongoing revolution.
