Perfect quantum state transfer of hard-core bosons on weighted path graphs
Steven J. Large, Michael S. Underwood, David L. Feder
The ability to accurately transfer quantum information through networks is an important primitive in distributed quantum systems. While perfect quantum state transfer (PST) can be…
Bose-Hubbard model for universal quantum walk-based computation
Michael S. Underwood, David L. Feder
We present a novel scheme for universal quantum computation based on spinless interacting bosonic quantum walkers on a piecewise-constant graph, described by the two-dimensional Bo…
Single-qubit unitary gates by graph scattering
Benjamin A. Blumer, Michael S. Underwood, David L. Feder
We consider the effects of plane-wave states scattering off finite graphs, as an approach to implementing single-qubit unitary operations within the continuous-time quantum walk fr…
Universal quantum computation by discontinuous quantum walk
Michael S. Underwood, David L. Feder
Quantum walks are the quantum-mechanical analog of random walks, in which a quantum `walker' evolves between initial and final states by traversing the edges of a graph, either in…
Fermi-Frenet coordinates for space-like curves
Michael S. Underwood, Karl-Peter Marzlin
We generalize Fermi coordinates, which correspond to an adapted set of coordinates describing the vicinity of an observer's worldline, to the worldsheet of an arbitrary spatial cur…
