We achieve a much greater degree of efficiency and a simpler implementation than previous proposals. We follow the "cluster state" measurement based quantum computational approach, and show how cluster states may be efficiently generated from pairs of maximally polarization entangled photons using linear optical elements. We demonstrate the universality and usefulness of generic parity measurements, as well as introducing the use of redundant encoding of qubits to enable utilization of destructive measurements-both features of use in a more general context. date: 2005-07-01 publisher: AMERICAN PHYSICAL SOC official_url: http://dx.doi.org/10.1103/PhysRevLett.95.010501 vfaculties: VMPS oa_status: green language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_batch elements_source: Web of Science elements_id: 83427 doi: 10.1103/PhysRevLett.95.010501 language_elements: EN lyricists_name: Browne, Daniel lyricists_id: DEBRO32 full_text_status: public publication: PHYS REV LETT volume: 95 number: 1 article_number: 010501 issn: 0031-9007 citation: Browne, DE; Rudolph, T; (2005) Resource-efficient linear optical quantum computation.
