FBH Offers Diamond Processing For Quantum Technologies

Insider Brief

• FBH offers a diamond processing platform to develop nanoscale components for quantum communication, sensing and information processing.
• Customers can commission surface preparation, ion implantation to create color centers, and nanoscale pillar fabrication separately or in combination.
• The platform aims to establish reproducible, scalable processes and integrate diamond nanostructures with photonic circuits.

PRESS RELEASE — Diamond is attracting growing interest for quantum technologies. Defects in its crystal lattice, known as color centers, can behave like individual atoms. Their discrete spin states can be addressed through optical transitions, making them promising building blocks for quantum memories and light sources for quantum communication and sensing.

Translating these properties into functional devices, however, requires diamond itself to be processed with particularly high precision. Compared with established semiconductor technologies, nanostructuring of diamond remains relatively unexplored. At FBH, the Joint Lab Diamond Nanophotonics with Humboldt-Universität zu Berlin combines semiconductor process technology with expertise in quantum optics and solid-state nanosystems.
