On a microscopic level the universe is governed by quantum physics. This is a strange wonderland where things are not as they seem. Objects can be in two places at once, cats can be both alive and dead, and objects can pass straight through walls. One of the most unsettling aspects of quantum physics is that it has at its very heart the idea that the universe is fundamentally uncertain. I will discuss the nature of this uncertainty and show how, far from being a hindrance, it can be put to use in a range of cutting edge new technologies. These include the codes that cannot be cracked, a new generation of superfast computers, and the ability to teleport objects over large distances.
