Hi All,
The talk today at 11am in the division room will be shared by all of our three visitors,
and has the following abstract:

Advances in integrated quantum photonics
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.
