Abstract

We are developing technologies based on nitrogen-vacancy centres (NVCs) in diamond for both quantum computing and magnetometry. Here I will focus on the latter: our fibre-coupled NVC-ensemble magnetometer has an unshielded sensitivity of 100 pT/√Hz in the frequency range of 10 150 Hz at room temperature. Fibre coupling means the sensor can be conveniently brought within 2 mm of the object under study. We aim to detect the magnetic fields created by the heart for medical diagnostics: magnetocardiography. By modifying our magnetometer we have imaged damage in steel which could be useful for finding corrosion.
