Quantum mechanics was developed in the early 20th century to describe nature in the small - at the scale of atoms and elementary particles. For over a century it has provided the foundation of our understanding of the physical world, including the interaction of light and matter,and led to ubiquitous1 inventions such as lasers and semiconductor , transistors. Despite a century of research , the quantum world still remains mysterious 2 and far removed from our experiences based on everyday life. A second revolution is currently under way with the goal of putting our growing understanding of these mysteries to use by actually controlling nature and harnessing 3 the benefits of the weird and wondrous properties of quantum mechanics. One of the most striking 4 of these is the tremendous computing power of quantum computers, where actual experimental realisation is one of the great challenges
