What is diamond quantum computing?
Diamond quantum computing is a field of quantum computing that is based on the process called optically detected magnetic resonance with the NV defect. It is observed when measuring a change in fluorescence after shining green light on an NV defect, or on an ensemble of them while scanning an applied microwave field. It’s too early to say (like with all the other qubit modalities) which approach is likely to succeed first in building a quantum computer that is actually useful, but at the moment NV center in diamond quantum computing technology is a long shot as most companies are either low-key about their findings, newer to the industry or very much in stealth mode.
5 Companies Working With Diamond Quantum Computing
1. Quantum Brilliance
Founded in 2019 by Andrew Horsley, Marcus Doherty, Mark Luo, and Mark Mattingley Scott, Quantum Brilliance is a venture-backed Australian-German quantum hardware company, providing diamond quantum computing accelerators supported by a full stack of software and application tools.
Quantum Brilliance’s vision is to enable mass deployment of quantum accelerators will propel industries to harness edge-computing applications and next-generation supercomputers, as the remarkable properties of the nitrogen vacancy (NV) centre in diamonds has the longest coherence time of any room temperature quantum state, meaning that as qubits they can operate anywhere a classical computer can.
And that’s a game-changer.
The startup’s international partnerships extend into North America, Europe and the Asia Pacific, working with governments, supercomputing centres, research organizations and industry leaders.
Diatope develops and produces engineered diamonds with NV center quantum computing sensing and quantum computing applications. Its vision of an enabling quantum platform has led to its establishment of a company dedicated to the development of engineered diamond hardware for quantum sensing and computing applications.
This diamond quantum computing company was founded in 2021 as a spinoff from the Institute for Quantum Optics at Ulm University by Johannes Lang, Christoph Findler and Christian Osterkamp, Diatope is driving the technology by supporting customers with its solutions and its deep knowledge of colour centres in diamond.
3. Quantum Diamond Tech
Quantum Diamond Tech Inc. (QDTI) is a Sommerville, Massachusetts-based startup founded in 2015 by John Pena that leverages NV magnetic imaging technology to create a novel, ultrasensitive biomaterial detection and diagnostics platform.
Based on world-leading research at Harvard University, QDTI is exploiting quantum systems engineered into diamond crystal — called nitrogen vacancy (NV) centres. These NV centres are the engine that will power the novel approach to biomolecule detection.
NVision works on new advances in diamond quantum physics (the transformative features of nitrogen vacancies in diamonds) to fundamentally change molecular analysis and medical imaging.
Founded in 2015 by Alex Retzker, Fedor Jelezko, Ilai Schwartz, Martin Plenio, and Sella Brosh, NVision is the diamond quantum computing company that emerged as the spinoff from the institutes of Theoretical Physics and Quantum Optics at the University of Ulm, Germany, and the NVision team combines world-leading scientists and business entrepreneurship.
5. Element Six
Element Six is a global leader in the design, development and production of synthetic diamond advanced materials. Part of the De Beers Group, Element Six is an independently managed global company NV center quantum computing with primary manufacturing facilities in Ireland, Germany, South Africa, the US and the UK.
Element Six synthetic diamond supermaterials are used in industrial applications such as cutting, grinding, drilling, shearing and polishing, while the extreme properties of synthetic diamond beyond hardness are opening up new applications in a wide array of industries such as optics, power transmission, water treatment, semiconductors and sensors.
In September 2021, Element Six launched DNV-B14™, (designed to provide the end-user with a uniform and high density of NV spin centres), its newest general-purpose chemical vapour deposition (CVD) quantum-grade diamond, an ideal material for quantum technologies such as magnetic field devices, RF sensors, solid-state gyroscopes and room temperature masers.
This breakthrough expands the company’s range of advanced materials for emerging quantum technologies.
