  bibo_abstract:
  - The biphoton correlation time, a measure for the conditional uncertainty in the
    temporal arrival of two photons from a photon pair source, is a key performance
    identifier for many quantum spectroscopy applications, with shorter correlation
    times typically yielding better performance. Furthermore, it provides fundamental
    insight into the effects of dispersion on the biphoton state. Here, we show that
    a characteristic dependence of the width of the temporal interferogram can be
    exploited to obtain insights into the amount of second-order dispersion inside
    the interferometer and to retrieve actual and Fourier-limited ultrashort biphoton
    correlation times of around 100 fs. In the presented scheme, we simultaneously
    measure spectral and temporal interferograms at the output of an SU(1,1) interferometer
    based on an integrated broadband parametric down conversion source in a Ti:LiNbO3
    waveguide.@eng
