title = "Comparison of quantum CPT and EPR magnetometers",
abstract = "Experimentally compared for the first time is the sensitivity of two magnetometer types implemented on a common base of rubidium atomic clock with coherent population trapping (CPT). The first magnetometer used a magneto-sensitive optically excited CPT resonance, the other measured field strength through the electron paramagnetic resonance (EPR) excited with alternating magnetic field. We show advantages and limitations of these promising quantum sensing technologies. Sensitivity of both types was measured under resonance excitation on the D1 line of 87Rb. We demonstrate that the Crossed D sign¡Crossed D sign Crossed D sign¢ magnetometer sensitivity may exceed that of the EPR device by two orders of magnitude. ",
