    "abstract": "We analyze systematic (classical) and fundamental (quantum) limitations of\nthe sensitivity of optical magnetometers resulting from ac-Stark shifts. We\nshow that in contrast to absorption-based techniques, the signal reduction\nassociated with classical broadening can be compensated in magnetometers based\non phase measurements using electromagnetically induced transparency (EIT).\nHowever due to ac-Stark associated quantum noise the signal-to-noise ratio of\nEIT-based magnetometers attains a maximum value at a certain laser intensity.\nThis value is independent on the quantum statistics of the light and defines a\nstandard quantum limit of sensitivity. We demonstrate that an EIT-based optical\nmagnetometer in Faraday configuration is the best candidate to achieve the\nhighest sensitivity of magnetic field detection and give a detailed analysis of\nsuch a device.",
