Published purpose

This proposal forms part of the Quantum Photonic Integrated Circuits for Quantum Interconnects Small Teams, Round 2 (2020) project whose overarching goal is to develop a chip-based platform where entangled photons can be generated and distributed between nodes in a quantum network, using nanowire-based quantum dots fully integrated on a chip manufactured in the silicon nitride material platform. In this part of the project being delivered by Queens’ University, the objective is to develop designs and techniques that will realize the full potential of a fully integrated platform for the generation and manipulation ofquantum light. The project targets two related activities: 1- The design of photonic structures in the silicon nitride material system that harness cavity quantum electrodynamic effects mitigatepotential decoherence mechanisms in semiconductor-based quantum emitters. 2 - The development of device structures and techniques that can be used to study emitter-emitter interactions mediated by the surrounding photonic environment and even exploit them to enhance the single photon source figures of merit.
