A Practical Scheme for Entanglement Concentration
arXiv:quant-ph/0104039 · doi:10.1103/PhysRevA.64.014301
Abstract
We present a realistic purification scheme for pure non-maximally entangled states. In the scheme, Alice and Bob at two distant parties first start with two shared but less entangled photon pairs to produce a conditional four-photon GHZ state, then perform a 45-degree polarization measurement onto one of the two photons at each party such that the remaining two photons are projected onto a maximally entangled state.
