#A quantum sensor for nanoscale electron transport The word defect doesnt usually have a good connotation--often indicating failure.
Graphic depiction of NV center sensors (red glowing spheres) used to probe electron motion in a conductor.
Here, each NV center is used as a sensor that can be thought of as switching between two states
1 and 0. The sensor can be calibrated in the presence of a constant magnetic field such that it is in state 1
. If the sensor experiences an oscillating magnetic field, the sensor switches to state 0. There is one more important component to this sensor--it can detect magnetic field strength as well.
For weak magnetic field fluctuations, the NV sensor will slowly decay to state 0; for stronger fluctuations, it will decay much faster from 1 to 0. By detecting different decay times,
physicists can precisely measure the fluctuating magnetic fields, which tells them about the electron behavior at a very small length scale.
