Synthetic Diamond for use in Quantum/Magnetometry

Synthetic diamond-enabled quantum computers could potentially solve problems that would not be possible with standard computers.

Element Six offers a range of products that are being utilised in the research field to develop synthetic diamond-based quantum applications. Depending on the application, this includes electronic grade single crystal CVD with extremely low levels of impurities (<0.05 ppb) all the way to HPHT (high pressure high temperature) synthetic diamond with very high levels of nitrogen dopants (>100 ppm).

Synthetic diamond has recently emerged as a candidate material for a range of quantum-based applications including: secure quantum communication, quantum computing and magnetic/electric field sensing. Quantum applications use the extreme world of quantum physics to perform operations that are not possible in systems following classical physics.

In quantum-based applications, the synthetic diamond acts as a host for impurities or defects, acting like a solid state atom trap. The quantum properties of these impurities, such as the Nitrogen-Vacancy defect, can be individually manipulated and made to interact, and photons of light emitted from these impurities can be used to read out their quantum information.

Synthetic diamond offers advantages over competitive materials as the quantum properties of the defects it hosts can be manipulated and probed at room temperature.

In quantum computing, synthetic diamond can be used as quantum bits or qubits (analogous to 1 and 0 in classical computers), which could potentially allow quantum computers to solve certain problems that would not be possible with standard computers.

For magnetic field sensing, synthetic diamond’s quantum properties can be used to detect very small magnetic fields. Synthetic diamond-based magnetometers have a wide field of potential applications, such as detecting magnetic fields associated with the ion flow through membrane channels in cells, an application which has important implications for drug development.
