  title = {Quantum-Noise-Limited Optical Frequency Comb Spectroscopy},
  abstract = {We achieve a quantum-noise-limited absorption sensitivity of 1.7×10-12  cm-1 per spectral element at 400 s of acquisition time with cavity-enhanced frequency comb spectroscopy, the highest demonstrated for a comb-based technique. The system comprises a frequency comb locked to a high-finesse cavity and a fast-scanning Fourier transform spectrometer with an ultralow-noise autobalancing detector. Spectra with a signal-to-noise ratio above 1000 and a resolution of 380 MHz are acquired within a few seconds. The measured absorption line shapes are in excellent agreement with theoretical predictions.},
