Was a fine show and people use that adjective-noun pair wrongly. A quantum leap is the smallest change possible. Yet we use it to represent a massive change. Paradoxical. The sound of the pair givens the ear the opposite meaning. keep smokin' I jest got me a glass blunt which works marvelously.
I think it meant it as a very small change in a complex system can lead to massive changes in a very short time. Of course it could also be another name for quantum tunneling. which is something completely different.
