    "abstract": "We demonstrate two key components for optical quantum information processing:\na bright source of heralded single photons; and a bright source of entangled\nphoton pairs. A pair of pump photons produces a correlated pair of photons at\nwidely spaced wavelengths (583 nm and 900 nm), via a $\\chi^{(3)}$ four-wave\nmixing process. We demonstrate a non-classical interference between heralded\nphotons from independent sources with a visibility of 95%, and an entangled\nphoton pair source, with a fidelity of 89% with a Bell state.",
