Researchers in the Netherlands and Australia have made the first “intelligent” quantum sensor based on the spin of a single electron trapped in a diamond nitrogen-vacancy centre. The device can measure magnetic fields at the very limits allowed by quantum physics, and if made to work at room temperature could be used to rapidly image the structure of single molecules, something that will be useful for medical diagnostics or developing new pharmaceuticals. It may also be able to map the weak magnetic fields generated by currents in micro and nanoelectronics devices, which could help in the design of better integrated circuits……..
