This time on the Function Room. It's the little things. The really little things. As Ruby(5) and Lily(3) theorise about the computers a fairy might use, I talk to UCD's John Sheekey about Quantum Computers. I got thinking about it before Christmas when Chinese scientists announced another quantum computing breakthrough.Those brand new heavies that may help humanity heal itself and even the planet but also could mean your money isn't as safe as it was online. Listen to me trying to fit enormous concepts inside my tiny brain, find out about Coding Theory and how a man in a Maths and Stats department in Dublin is trying to stay one step ahead of The Quantum Menace (my hyperbole) armed with pens, paper, markers, whiteboard in an office that doesn't have a window. (news clips from https://www.youtube.com/watch?v=E5MBAJJU9Hk )
