In this course, we investigate possible answers to these questions, and form an understanding as to why these questions matter. In particular, we look at recent work which views quantum theory as a theory of information manipulation, and see that this provides extraordinary new insights into the nature of physical reality, which leads to new technological possibilities (such as quantum cryptography and entanglement-assisted computation) that harness quantum weirdness, and even helps us to derive the mathematics of quantum theory from simple physical assumptions.
