英文摘要	We propose a cavity QED system with two-photon Doppler-free configuration for weak magnetic field detection with high sensitivity at room temperature based on cavity electromagnetically induced transparency. Owing to the destructive interference induced by the control and driving fields, two transparency channels are opened. The Faraday rotation within two transparency channels can be used to detect weak magnetic field with high sensitivity at room temperature. The sensitivity with single photon and multiphoton probe inputs is analyzed. With single photon measurement, our numerical calculations demonstrate that the sensitivity with 3.8 nT/root Hz and 6.4 nT/root Hz could be achieved. When we measure the magnetic field with multiphoton input, the sensitivity can be improved to 7.7 fT/root Hz and 25.6 fT/root Hz under the realistic experimental conditions. (C) 2016 Elsevier B.V.
