Efficient linear optical quantum computation
Dan E. Browne, Terry Rudolph · arXiv (Cornell University) · 2004
We introduce a new scheme for linear optics quantum computation, with 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, most importantly polarizing beam splitters and photon counters.
