Abstract

We demonstrate two key components for optical quantum information processing: a bright source of heralded single photons; and a bright source of entangled photon pairs. A pair of pump photons produces a correlated pair of photons at widely spaced wavelengths (583 nm and 900 nm), via a χ(3) four-wave mixing process. We demonstrate nonclassical interference between heralded photons from independent sources with a visibility of 95&% (after correction for background), and an entangled photon pair source, with a fidelity of 89&% with a Bell state.
