PROJECT DETAILS:

The growing number of applications in quantum technologies requires a reliable source of materials capable of exhibiting quantum properties. Diamond is one such material that, when doped with specific impurities such as nitrogen, can display quantum characteristics. A key advantage of diamond is that these quantum properties can be used at room temperature, unlike some other materials that require cooling to approximately −270 °C. Because natural diamond is not a reliable source, it is essential to synthesize diamond with controlled technical properties for targeted applications.

This project aims to design and build industrial-scale prototypes for the synthesis of pure diamond as well as diamond with precisely controlled doping characteristics using plasma technology.

The main outcome for PLASMIONIQUE will be the development of an industrial-scale reactor prototype for the synthesis of pure diamond and diamond substrates for room-temperature quantum technology applications, as well as other uses. The benefits for the other industrial partner include access to a technology developed in Quebec for the synthesis of pure diamond and the production of diamond substrates for quantum technology applications. The product will be commercialized internationally for technology developers.

For Quebec, this project supports the creation of a new global industry focused on supplying the base materials required for the development of products using room-temperature quantum technologies. The reactor also offers the opportunity to synthesize high-purity technological diamond, providing an environmentally friendly alternative to natural diamond. As a result, two Quebec-based companies would become the first in Canada to develop reactors and laboratory-grown diamonds for quantum technology and jewelry applications.
