Engineering Photonic Quantum Technologies

Engineering Photonic Quantum Technologies Programme Grant

The “Engineering Photonic Quantum Technologies” Programme Grant goes significantly beyond previous achievements in the quantum technology field. Now that the project is reaching the end of its 5 year journey, we warmly invite you to celebrate its achievements with us.

The programme is led by the University of Bristol and is a collaboration between leading experts and skilled researchers from the Universities of Bristol, Glasgow, Heriot-Watt and Imperial College London.

This consortium has led the international development of the key components of single photon sources, detectors, and quantum photonic circuits. We originated the integrated quantum photonics approach to assembling these components on a photonic chip, showing that: single photons can be generated in novel waveguide structures; high-fidelity, miniaturised circuits can be implemented in waveguides on-chip; and single photon detectors can be used for high performance operation. In parallel we have been instrumental in developing the underpinning theory of quantum computing linking to proof-of-principle experiments, as well as beginning to address the vital issues of system integration and control.

The impact of the Programme Grant is probably best measured by its output and knowledge transfer. To date, the grant has already had significant reach with exploitation resulting in three start-up companies, three patents and representation at multiple Science outreach events in the UK and beyond. Work carried out has resulted in over 70 journal publications (including papers in Science, Nature Photonics, Nature Communications, PRL, APL and IEEE) and over 140 conference presentations and papers. The programme has been a great success and today we want to show you how the research provides a basis for future developments in the UK. Therefore, on behalf of the consortium, I welcome you and sincerely hope you enjoy the day.

Quantum mechanics describes a microscopic world that is fundamentally probabilistic, where a single object can be in a superposition of two places at once and where two far apart entangled objects can instantaneously influence each other. Attention during the programme has focused on the potential for harnessing these counterintuitive properties for dramatic increases in the power and functionality of information and communication tasks - quantum technologies (QTs).

Our vision for this Programme Grant is to build a fully integrated photonic quantum technology platform for applications in quantum computing consisting of compact and complex integrated quantum circuits containing 1000’s of discrete optical elements and we are pleased to share our research with you.
