Our technology
Small and powerful: a new era of quantum sensing
Our cutting-edge magnetic-field quantum sensing technology harnesses the power of quantum physics to enable measurements with unmatched precision. Combining extraordinary sensitivity with a compact form factor, our sensors are destined to transform a wide range of applications across numerous industries.
Magnetic-field quantum sensors surpass the capabilities of conventional sensors by offering a wider measurement range, higher sensitivity, and higher spatial resolution – all while being remarkably robust, non-invasive, and easy to set up. This unique combination makes our technology ideal for applications requiring superior precision and minimal disruption.
Moreover, our magnetic-field quantum sensors hold significant advantages over earlier quantum sensing techniques like SQUIDs (superconducting quantum interference device), vapor cells, or optical traps. While these methods have proven effective, they often require large, complex setups with limited flexibility. In contrast, our magnetic-field quantum sensors offer similar performance in a much smaller, more versatile, and cost-effective package – unlocking new possibilities for sensing applications that were previously unattainable.

Quantum sensing with NV diamonds
How our sensors work
Our quantum sensing magnetometer uses a diamond as the core sensing element. This diamond has nitrogen atoms added as a defect, known as NV centers. These nitrogen-vacancy centers are remarkable, as the extra nitrogen atoms provide additional electrons acting as tiny magnetic field sensing elements.
These NV centers change the diamond’s optical and electronic properties. When green laser light is shone on the diamond through an optical focusing unit, it excites the electrons within the NV centers to a higher energy level. As the electrons return to their ground state, they emit photons, visible as red light, which is separated through an optical filter and then detected by a photodiode.
The key phenomenon, however, is that the energy levels of the NV centers are highly sensitive to changes in the external magnetic field, which enables them to be used as a quantum based on the Zeeman effect. These quantum states are accessible via microwave radiation. When electrons occupy these levels and are excited by the green laser light, they no longer decay by emitting red photons but instead remain "dark." By varying the frequency of the microwave radiation and observing changes in the intensity of the emitted red light, we can precisely determine the strength of the external magnetic field.
