Diamonds are not just for jewellery anymore. Researchers at the University of Luxembourg, in collaboration with international partners, are uncovering groundbreaking applications for diamonds in quantum technologies and medical imaging.
By introducing boron atoms into diamonds, these typically insulating materials transform into conductors, enabling unique interactions with electromagnetic waves.
This innovation paves the way for advancements in quantum computing, optics, and cryptography Boron-doped diamonds offer precise control over photons, the smallest units of light, which is essential for developing reliable quantum devices.
Cross-sector research
Beyond physics, these diamonds hold promise in medicine, where nanoscale diamond particles could enhance imaging techniques, helping doctors visualise tissues and cells with unprecedented clarity.
Looking ahead, the University of Luxembourg is exploring how diamond nanoparticles interact with vibrations to potentially power optical quantum computers. Despite challenges like decoherence, projects like QUANCOM aim to deepen understanding and mitigate disruptions in quantum systems.
Luxembourg’s innovation-driven economy stands to benefit from this cross-sector research, bridging science and industry.
