Summary:
- This article discusses the development of a new type of quantum sensor that can detect extremely weak magnetic fields with high precision.
- The sensor is based on the use of nitrogen-vacancy (NV) centers in diamond, which can act as sensitive magnetometers when exposed to a magnetic field.
- The researchers demonstrate that this NV-based sensor can be used to measure the magnetic fields generated by the human brain, opening up new possibilities for non-invasive brain imaging and diagnostics.
