Journal ArticleDOI
A one-way quantum computer.
TL;DR: A scheme of quantum computation that consists entirely of one-qubit measurements on a particular class of entangled states, the cluster states, which are thus one-way quantum computers and the measurements form the program.
Journal ArticleDOI
Quantum Repeaters: The Role of Imperfect Local Operations in Quantum Communication
TL;DR: This work presents a scheme of a quantum repeater that connects a string of (imperfect) entangled pairs of particles by using a novel nested purification protocol, thereby creating a single distant pair of high fidelity.
Journal ArticleDOI
Persistent entanglement in arrays of interacting particles.
TL;DR: These states can be regarded as an entanglement resource since one can generate a family of other multiparticle entangled states such as the generalized Greenberger-Horne-Zeilinger states of
Journal ArticleDOI
Measurement-based quantum computation on cluster states
TL;DR: This work gives a detailed account of the one-way quantum computer, a scheme of quantum computation that consists entirely of one-qubit measurements on a particular class of entangled states, the cluster states, and proves its universality.
Journal ArticleDOI
Multiparty entanglement in graph states
TL;DR: This work characterize and quantify the genuine multiparticle entanglement of such graph states in terms of the Schmidt measure, to which it provides upper and lower bounds in graph theoretical terms.
