Qnami - Diamond Quantum Probes

DP-QUANT1 for Nanoscale MRI

QNAMI applies the NV-center physics to sensing. By precisely controlling and measuring the state of a single electron, they are able to measure electric and magnetic fields with excellent sensitivity. Furthermore, the nano-sensors produce images with unique resolution on the nano-meter scale. This quantum sensing technique is being developed in the external page quantum sensing group in Basel.

 

 

 

NV-centers are tiny defects that can be artificially implanted into the diamond crystal lattice. They trap an electron, which is used as a quantum sensor. The color centers in diamond present a number of advantages. As their name suggests, they emit light in the visible range. It is used for signal read-out. They also display very long coherence times, a key parameter for quantum applications.
