Introduction

Abstract

Fundamental quantum physics and quantum information science has found great experimental success through control over single photons in optical circuits. To date, however, the majority of quantum optical experiments use large scale (bulk) optical elements bolted down to an optical bench; an approach that ultimately limits the complexity and stability of quantum circuits required for quantum science and technology (QST). Here, a series of experiments are reported in the emerging field of integrated quantum photonics that show monolithic waveguide chips to be a suitable platform for realising the next generation of quantum optical circuits. These demonstrations are foundational in developing a new quantum photonic platform necessary for studying fundamental quantum physics and for advancing quantum information science and technology.KeywordsQuantum CircuitQuantum WalkSingle QubitQuantum TechnologySilicon OxynitrideThese keywords were added by machine and not by the authors.
