It is in the laws of how quantum systems register and process information that we are to find the measure of the universe. Men used to measure distance by the length between their elbow and outstretched fingers — the cubit. Now we measure distances by the information contained in the light emitted by two-level atoms— the quantum bit or qubit.Seth Lloyd

Seth Lloyd flew down from Cambridge as the keynote speaker at the Edge Qubit dinner. He was supposed to talk about quantum search engine algorithms. But he forgot. Steve Lohr, technology correspondent at The New York Times was there and noted:

"I've chatted with Seth before, of course, and even quoted him, but I've never talked to him at this length. He's a stitch. My personal favorite was his description of teaching quantum computing to first graders: 'Arms up, arms down.'"
