Deterministic qubit transfer between orbital and spin angular momentum of single photons
arXiv:1109.6747 · doi:10.1364/OL.37.000172
Abstract
In this work we experimentally implement a deterministic transfer of a generic qubit initially encoded in the orbital angular momentum of a single photon to its polarization. Such transfer of quantum information, completely reversible, has been implemented adopting a electrically tunable q-plate device and a Sagnac interferomenter with a Dove's prism. The adopted scheme exhibits a high fidelity and low losses.
