Element Six, headquartered in Didcot, Oxfordshire, UK, has written a feature titled ‘The diamond quantum  revolution’ in the April edition of Physics World, in which Matthew Markham, the company’s Principal Research Scientist, and Daniel Twitchen, Sales Director, CVD, explore the practical quantum applications of Element Six’s engineered chemical vapour deposition (CVD) diamond solutions. 

Diamond has very diverse properties and is used in a broad spectrum of applications, including the machining of smartphones, high-power lasers for automotive manufacturing and high-end audio systems. 

Due to continued scientific progress in the optimisation of Element Six’s CVD process, synthetic diamond materials with engineered levels of QuBits made up of nitrogen vacancy (NV) defects are said to be leading the way in enabling quantum technologies such as magnetic sensing devices.

Current quantum technology research covers a range of areas including sensing, networking and information processing, with the potential to impact the healthcare and automotive industries, as well as the development of new materials. Diamond’s room temperature operation, the accessibility of material and the simplicity of the components have enabled the development of numerous quantum device proposals with the potential of fostering multiple applications.

“As we enter the fourth industrial revolution, diamond science and technology are at the forefront of research,” explained the company. “Element Six’s role in the transfer of these technological breakthroughs from our research labs into start-up and established businesses is imperative in creating diamond quantum-based devices of the future.”
