    "abstract": "We show that the coined quantum walk on a line can be understood as an\ninterference phenomenon, can be classically implemented, and indeed already has\nbeen. The walk is essentially two independent walks associated with the\ndifferent coin sides, coupled only at initiation. There is a simple analogy\nbetween the evolution of walker positions and the propagation of light in a\ndispersive optical fiber.",
