Quantum computation will unlock a new class of computational complexity, allowing us to solve previously unsolvable problems, and understand previously unconscionable phenomena. A quantum computer must exert precise control over complex quantum systems, on a truly massive scale. It must freely wield entanglement- the ethereal connection between quantum particles-to operate. Photons, particles of light, have obvious use in the transmission of quantum information, but could also process it; their manipulation is aided by a millennium of human experience with optics. This thesis describes how to build a photonic quantum computer from the ground up, and applies today's most scalable optical technology-silicon integrated optics-to construct the first integrated devices which can produce photons and wield their entanglement. I detail the nonlinear process used to produce photons, spontaneous four-wave mixing, as well as the silicon optical technology used to control them. I demonstrate, via four experiments, a massive scaling-up of silicon quantum photonics. Finally, I provide a glimpse of possible technological routes towards universal quantum computation with photons.
