What is so strange about quantum mechanics? Before the advent of quantum information, there were many good answers to this question. With the development of fields such as quantum encryption and quantum computing, more sophisticated answers are now needed. There is thriving research into the foundational structure of quantum theory. 

We tackle questions such as: How does quantum reality differ from classical reality? What causes the transition from quantum to classical worlds? How do we describe the loss of quantum effects? What makes quantum technology outperform its classical counterpart? In particular, how do we achieve quantum advantages in quantum computing and simulations? How does relativity affect quantum physics? How do we understand thermodynamics in quantum mechanics? 

Remarkably such questions can be cast into precise mathematical terms, and we can arrive at concrete answers through the language of quantum information. Beyond the conceptual value, these results also find applications in a range of new and remarkable practical tasks in quantum information science.
