Abstract
Quantum information theory has emerged as one of the frontier areas of research that not only aims to offer radically new ways of processing information but also offers new inights into the nature of quantum world. However, if we ask what is quantum information, then the very notion of quantum information is not yet defined in a more fundamental way. It may be possible that we gain better and better understanding of quantum information by asking questions like what is so `quantum’ about quantum information and investigating essential differences between classical and quantum information. In this talk I will focus on these aspects and highlight some fundamental differences between them.
