A process for measuring multiple functions with a quantum sensor network includes: providing a plurality of quantum sensors, each of which is configured for measuring a different analytic function of a set of unknown parameters; preparing the plurality of quantum sensors in a known state; exposing the plurality of quantum sensors to the set of unknown parameters; measuring the plurality of quantum sensors; and calculating the multiple analytic functions of the set of unknown parameters from the measurements of the plurality of quantum sensors.
This protocol can be used to measure properties of spatially varying fields such as magnetic fields, electric fields, gravitational fields, and temperature, with applications in fields such as chemistry, medicine, biology, materials science, physics, geodesy, and geophysics.
