From quantum mysteries to quantum technologies
Quantum theory is over 100 years old. In the early days, its consequences were often mapped out through “Gedankenexperiments” – imaginary experiments that reveal often bizarre and counter-intuitive phenomena. This way of thinking helped clarify some of the fundamental notions of quantum theory, but it was unimaginable that such scenarios could ever be realized in experiments. Today, not only have many such experiments become reality, they are also the basis of transformative new applications: quantum technologies that use and control unique quantum effects. In this lecture, we will discuss some of the puzzling basic effects of quantum physics, and how they are applied for modern quantum technologies.
