Member: Element Six (UK) Ltd.

Element Six (E6) designs, develops and produces synthetic diamond and tungsten carbide solutions.

Since 1959, E6’s focus has been on engineering and optimising the diamond synthesis process to unlock innovative, diamond-enabled applications, including ultra-precision machining, drilling, thermal management, optics, wastewater management and quantum-enabled sensing.

Element Six pioneered the development of single crystal diamond using the Chemical Vapour Deposition (CVD) method in the early 2000s.

With production facilities in the UK and California, the company has been at the forefront of a range of new developments in CVD diamond synthesis and associated industrial applications. Its patented technologies also drive a new production facility in Oregon, to supply gem-quality stones to Lightbox Jewelry.

Working closely with a network of global collaborators, Element Six’s engineered diamond research has accelerated the delivery of many breakthroughs in quantum research, including:

  • In 2012, Harvard reported isotopically engineered CVD single crystal achieved spin coherence times of seconds at room temperature.
  • Alongside Delft University of Technology in 2015, Element Six material enabled the first successful loophole-free Bell’s inequality test, proving for the first time that ‘spooky action at a distance’ is real. This also marked a significant technology step toward a quantum-secure enabled network.
  • In 2018, Imperial College London utilised engineered single crystal material in the development of the world’s first continuous-wave, room-temperature, solid-state MASER (microwave amplification by stimulated emission of radiation).
  • Lockheed Martin’s 2019 ‘Dark Ice’ program delivered a DNV-enabled magnetometer that measured the direction and strength of nearly imperceptible magnetic field anomalies, opening up diamond-based quantum devices in GPS-denied navigation applications.


  • Quantum demonstrations
  • Masers
  • Detection of RF radiation
  • Gyroscopes
  • Sensing
  • Any other project requiring nitrogen-vacancy (NV) ensembles
  • Foundamental quantum mechanics
  • Quantum computing
  • Nano temperature sensing
  • Nano magnetic field sensing


Further areas of interest include the consumer, defence and medical markets.


Electronic Grade Diamond

  • Single crystal CVD diamond with exceptionally low background spin impurity (<5 ppb)
  • T2 (Hahn echo) > 500 µs – the longest reported in a natural isotopic abundance synthetic diamond
  • Optimised synthesis and post-synthesis processing provide control at the part-per-billion level with typically 1 ppb of nitrogen
  • Ideal as a base material for single nitrogen-vacancy (NV) based quantum technologies such as quantum information processing and nano-magnetic field sensing



  • The first solution in Element Six’s DNV Series
  • An ideal starting material for those interested in researching nitrogen-vacancy (NV) ensembles
  • Aimed at lowering the barriers for the adoption of diamond in research and development for quantum applications
  • Contains a uniform density of NV spin centres
  • Specifically designed for emerging quantum diamond applications
  • Diamond can be controllably and reproducibly doped with nitrogen
  • Offers spin lifetimes of a microsecond
  • Spin qubits can be initialised and read out at room temperature
