This is a set of slides from a talk on introducing the Hamming distance into classical logical information theory and then developing the quantum logical notion of Hamming distance–which turns out to equal a standard notion of distance in quantum information theory, the Hilbert-Schmidt distance. Since this concept has then been shown to be derived from two quite different beginning points, it enhances its status as a natural notion of distance between quantum states (which includes its square root, trace distance).
