We report our latest work in integrated quantum photonics (IQP) within Silica-on-Silicon waveguide chips. Amongst several demonstrations, near-unit fidelity quantum interference and two-photon entangling logic operation, the first integrated quantum metrology experiments beating the standard quantum limit, a compiled version of Shor`s quantum factoring algorithm on a waveguide chip and multiport interferometers on integrated devices that rely on multimode interference are shown. Moving forward to new materials, arrays of 21 evanescently coupled waveguides, were fabricated in SiON chips to implement quantum walks and a generalised form of two-photon non-classical interference, which were observed via two photon correlation. All these demonstrations illustrate the importance of integrated optics for future quantum technology.
