Problem
Conventional magnetic‑field sensors such as SQUIDs, vapor‑cell devices, or optical traps are large, require complex infrastructure, and offer limited flexibility, making high‑precision field measurement difficult to integrate into industrial products.
Solution
Bosch Quantum converts laboratory‑grade quantum sensing into compact magnetic‑field sensors that can be deployed in portable or embedded applications. The core sensing element is a diamond containing nitrogen‑vacancy (NV) centers, whose energy levels shift in response to external magnetic fields. A green laser excites the NV centers, and red fluorescence modulated by microwave radiation is detected to quantify the field with high sensitivity. The resulting hardware is small, robust, non‑invasive, and easy to set up, providing a wider measurement range, higher spatial resolution, and greater accuracy than traditional sensors. This capability supports use cases in medical diagnostics, consumer electronics, navigation, resource exploration, and process optimization. Bosch leverages the Bosch Group’s manufacturing expertise to produce the sensors at industrial scale.
Target Audience
Primary customers are OEMs and system integrators in medical imaging, consumer device manufacturing, navigation and geophysical exploration, and industrial process control that require precise magnetic‑field measurements.
