    "abstract": "By pursuing the deep relation between the one-dimensional Dirac equation and\nquantum walks, the physical role of quantum interference in the latter is\nexplained. It is shown that the time evolution of the probability density of a\nquantum walker, initially localized on a lattice, is directly analogous to\nrelativistic wave-packet spreading. Analytic wave-packet solutions reveal a\nstriking connection between the discrete and continuous time quantum walks.",
