    "abstract": "A duality between the properties of many spinor bosons on a regular lattice\nand those of a single particle on a weighted graph reveals that a quantum\nparticle can traverse an infinite hierarchy of networks with perfect\nprobability in polynomial time, even as the number of nodes increases\nexponentially. The one-dimensional `quantum wire\u0027 and the hypercube are special\ncases in this construction, where the number of spin degrees of freedom is\nequal to one and the number of particles, respectively. An implementation of\nnear-perfect quantum state transfer across a weighted parallelepiped with\nultracold atoms in optical lattices is discussed.",
