We demonstrate that an integrated silicon microring resonator is capable of efficiently
producing photon pairs that are completely unentangled; such pairs are a key component of …

Single-photons with high spectro-temporal purity are an essential resource for quantum
photonic technologies. The highest reported purity up until now from a conventional silicon …

Integrated photonics is a powerful contender in the race for a fault-tolerant quantum
computer, claiming to be a platform capable of scaling to the necessary number of qubits …

We study the generation of Greenberger-Horne-Zeilinger (GHZ) states of three path-
encoded photons. Inspired by the seminal work of Bouwmeester et al.[Phys. Rev. Lett. 82 …

Optical microresonators are characterized by a comb of resonances that preserve similar
characteristics over a broad spectral interval. However, for many applications it is beneficial …

In this thesis I study in detail the quantum dynamics of several nonlinear optical processes in
microresonator systems. A Heisenberg-picture input-output formalism is developed from first …

We investigate the use of integrated structures for the efficient generation of squeezed light
via dual-pump spontaneous four-wave mixing. We consider the case of ring resonators, in …
