So, what are nitrogen vacancy diamonds? NV centres occur when the carbon lattice of a diamond is interrupted by a nitrogen atom and an adjacent void. This can occur naturally, but more often is specially engineered. The introduction of the nitrogen atom frees a single pair of electrons from the diamond’s chemical structure which allows SBQuantum to derive magnetic information from their spin.
Exciting this electron pair with a green laser, we can measure its quantum state as they interact with Earth’s magnetic field and output red light. The amount of red light allows us to map the earth’s magnetic field in that location. Not only does this allow us to see greater localized nuances, but by mapping this data onto a three-dimensional plot we unlock ‘Magnetic Intelligence’. Here, we use tensor gradiometry to increase the number of characteristics we can identify in objects. Further, we add our proprietary algorithms to discriminate environmental noise. We want to focus on the relevant features, not a car driving past down the road!
