Quantum Sensing Quantum Magnetometers Quantum magnetometers can detect incredibly small changes in magnetic fields by tapping into the strange and powerful features of quantum physics. these devices rely on the discrete nature and coherence of quantum particles—behaviors that give them a major edge over classical sensors. Quantum magnetometers rely on the precise measurement of magnetic fields to detect subtle changes in their surroundings. researchers have demonstrated the potential of using quantum computing hardware for sensing applications, including the detection of magnetic fields and electric currents.
Quantum Sensing Quantum Magnetometers Quantum magnetometers, particularly those based on nitrogen vacancy (nv) centers in diamonds, are among these innovations, offering a powerful alternative to conventional magnetic based systems. Here the authors report quantum sensing of dynamical magnetic fields with 1 ns time resolution using nv center magnetometry, which can be applied to studies of magnetization dynamics. This work proposes a novel approach for current measurement utilizing a nonlinear magneto optical rotation (nmor) atomic magnetometer, which is a quantum sensor designed to detect the magnetic field generated by current. This review focuses on the two room temperature quantum receiver platforms that presently have the clearest path to infrastructure sensing: optically pumped atomic magnetometers (opms) and nv center diamond magnetometers.

This review focuses on the two room temperature quantum receiver platforms that presently have the clearest path to infrastructure sensing: optically pumped atomic magnetometers (opms) and nv center diamond magnetometers. Our compact diamond quantum magnetometers provide high sensitivity, vector magnetic sensing to detect subtle magnetic changes with low noise and minimal drift, while operating passively in ambient conditions. Quantum magnetometry is the most commercially advanced quantum sensing application. nv center magnetometers and optically pumped magnetometers (opms) detect magnetic fields with sensitivities in the femtotesla range — roughly one billionth of earth's magnetic field. The sensing of a magnetic field with ultra high sensitivity can be achieved using quantum magnetometers, which are based on the quantum natures of micro particles. The purpose of this document is to give a brief technical overview of the types of quantum magnetometers available, their operating principles and some of the guidelines for using these systems in real world geophysical environments.
