ABSTRACT
My intention in this chapter is not to give a full and comprehensive description of quantum information but to try to give some insights into ways in which thinking about information in the world of quantum physics is forced to differ from the traditional classical perspective. When I refer to quantum information as a field, I include general aspects such as quantum computing and any system where the information is stored or transferred as quantum states. I will briefly describe how measurements on quantum systems are interpreted and give some idea of their consequences when applied to such things as the construction of logic gates, encryption and computing.
