Ok - so what exactly *is* quantum computing?

We all love the Perimeter Institute, and our tax money is flowing into Waterloo to make quantum computing real, and it certainly sounds gee-whiz, but what exactly is it? CBC went to find out:

CBC: What are the practical applications of quantum computing?

RL: The first application is computing more efficiently and faster. It also leads to other types of technologies, like quantum cryptography—new ways of encrypting information and ensuring it is private, so people can’t eavesdrop. A third piece of the technology is sensors that are a lot more sensitive to things around us. Quantum sensors will be able to sense things that sensors today can’t, whether that is a sensor in your thermostat, in your car to regulate airflow or on airplanes to know what speed it is moving at.
