*Physics is perceived as a lonesome, nerdy kind of enterprise that has very little to do with human feelings and the things that excite people day-to-day about each other. Yet physicists in their own working environment are very social creatures.
*(Leonard Susskind)

**Quantum information theory** is a new interdisciplinary branch of quantum physics, information theory, and mathematics. Here we learn to deal with the strange world of quantum phenomena from a completely different perspective. We as physicists are trained to think in terms of physical objects and symmetries. Quantum information theory takes a more abstract point of view. Like information scientists, who invented the bit as the smallest information unit, quantum information theory deals with the quantum bit (qubit) as the smallest entity of a quantum system. Quantum theory is much more than plugging quantum gates on the switchboard of a (non yet existing) quantum computer. It is a different way to learn about quantum mechanics, and to appreciate this theory as the most fundamental theory ever created by humanity.
