**A PHY 449/449Y Introduction to Quantum Foundations and Quantum Information (3)
**Quantum theory has many mysterious features, such as entanglement and the probabilistic nature of measurements, which seem to defy understanding in terms of the mechanistic clockwork picture of reality that underlies classical physics. What do these features suggest about the nature of physical reality? For example, is there really "spooky action at a distance" in Nature, as Einstein quipped? 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.
