The QT Assemble project aims to overcome technological barriers to create new markets in the exciting and ever-evolving field of quantum technologies.

The 14 collaborating companies aim to achieve this by increasing the reliability and reducing the size, weight, power, and cost of laser components and systems. This will both boost the UK presence in this emerging market and enable easier adoption of the technology in real-world applications. Covesion are a major contributor to the £10 million project and will use their expertise of PPLN technology to design and manufacture waveguides as standalone and integrated components for the project.

The QT Assemble project brings together collaborating partners including; the University of Southampton, Fraunhofer Centre for Applied Photonics, INEX Microtechnology, PowerPhotonic, Gooch and Housego, Photon Force, ColdQuanta UK, UniKLasers, RedWave Labs, Caledonian Photonics, Alter Technology Tuv Nord UK, and AegiQ.

The consortium of UK companies will combine their experience and industry knowledge to widen the exploitation of quantum technology in existing markets such as navigation and situational awareness, communications, and computing. The QT Assemble project will also stimulate more organisations and industries to utilise the benefits and new commercial opportunities available in the quantum market.

The programme will harness three major, innovative and disruptive integration and assembly processes including:

Waveguide writing

Ultrafast laser inscription, direct UV laser writing, and micromachining offers the possibility to define complex optical structures into any optically transparent material allowing for integration of complex active and passive QT components.

Nanoscale alignment

Precision transfer printing and nanoscale alignment allows for efficient coupling between laser diodes, non-linear elements, and single-photon detectors that are naturally present in different material systems.

Monolithic integration

Adhesion-free bonding and laser welding allows for robust integration of materials with the optimal thermal and optical interfaces.

The QT Assemble programme, starts in September 2020 and will run for 3 years.
