We report a practical non-postselection entanglement concentration scheme in which a maximally entangled Bell-state photon pair is produced from two pairs of partially (or non-maximally) entangled photons. Since this scheme is built only upon linear optical elements and does not require photon-number resolving detectors, it has immediate applications in experimental implementations of various quantum...
We report an entanglement concentration scheme in which a photon pair in the |Psi(-)> Bell-state is obtained from two pairs of partially (or non-maximally) . Our scheme is built upon linear optics only and does not require photon-number resolving detectors.
