Abstract
This paper demonstrates single-shot multi-parameter estimation of an optical frequency comb surpassing the standard quantum limit. A multi-pixel spectrally resolved (MPSR) apparatus simultaneously determines mean energy, central frequency, and spectral bandwidth of ultrafast pulses. Using a quantum frequency comb with multiple squeezed states, signal-to-noise ratios exceed the standard quantum limit. This approach is applicable to ultrafast quantum metrology and multimode quantum information processing.
