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 x, where xis a position without a quantum sensor of the plurality of quantum sensors; and estimate an amplitude of the field at the position xbased on the estimated function of the parameters.
