Bosch and Element Six, a synthetic diamond manufacturer under De Beers Group, have announced a joint venture to accelerate the commercialization of diamond-based quantum sensors. Element Six will take a 25% stake in Bosch Quantum Sensing, which was originally formed in-house by Bosch in 2022 and currently employs 30 staff in Ludwigsburg, Germany. The joint venture builds on a development collaboration between the companies initiated in 2023.
The sensors rely on engineered synthetic diamonds to detect extremely weak magnetic fields, a key requirement for precision sensing in fields such as medical diagnostics, inertial navigation, and resource exploration. Bosch will integrate the diamond components into scalable sensor systems, with the long-term goal of reducing size and cost to enable chip-level integration. The current prototype is smartphone-sized and designed to meet stringent sensitivity requirements in portable form factors.
The companies aim to scale production of quantum sensors for industrial use, addressing market segments where GPS-independent navigation and biomagnetic field detection are critical. Bosch projects that medical and mobility applications alone could represent a mid-single-digit billion-euro market by the 2030s. Final approval of the new joint venture is pending regulatory clearance.
