Purification of single-photon entanglement with linear optics
arXiv:0811.2953 · doi:10.1103/PhysRevA.78.050301
Abstract
We show that single-photon entangled states of the form |0>|1>+|1>|0> can be purified with a simple linear-optics based protocol, which is eminently feasible with current technology. Besides its conceptual interest, this result is relevant for attractive quantum repeater protocols.
