Extracting Biomagnetic Nerve Signals from Quantum Sensor Data

Background

Nerves generate magnetic fields when an action potential travels along them. Measuring these fields directly — rather than the electrical potentials picked up by electrodes — is attractive: the magnetic field passes through tissue essentially undistorted and requires no electrical contact with the sample. The catch is amplitude, as the field of a single nerve is in the nanotesla-to-picotesla range, orders of magnitude below the noise floor of a single measurement.
