Cost-Aware Online Switching of Four-Qubit Probe States for Quantum Magnetometry Under Non-Stationary Noise

Quantum magnetometry can be enhanced through the use of entangled probe states, yet the optimal probe selection depends greatly on the noise, readout errors, and costs involved in preparation. An analysis is given of a simulation of a four-qubit magnetic field estimation experiment where the optimal probe state is adap...
