Abstract: 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

Abstract: A system for the measurement of field properties includes a quantum system, a processor, and a memory. The quantum system includes a plurality of quantum sensors coupled to a field. Each sensor of the plurality of quantum sensors is located at a position in the field. The position depends on parameters. Each sensor of the plurality of quantum sensors is entangled. The memory includes instructions stored thereon, which, when executed by the processor, cause the quantum system to: access a signal of the quantum system; sense a plurality of interdependent a local field amplitudes corresponding to the plurality of quantum sensors by locally probing the field by each sensor of the plurality of quantum sensors; estimate a function of the parameters at a position x0, where x0 is a position without a quantum sensor of the plurality of quantum sensors; and estimate an amplitude of the field at the position x0 based on the estimated function of the parameters.
