• Abstract summary: Measuring the phase spectrum at the single-photon level is essential for the full characterization of the temporal-spectral mode of quantum sources. We present a phase retrieval algorithm-based method to recover the phase spectrum difference between two independent pulses from their Hong-Ou-Mandel interference pattern and intensity spectra.

• Abstract: Measuring the phase spectrum at the single-photon level is essential for the full characterization of the temporal-spectral mode of quantum sources. We present a phase retrieval algorithm-based method to recover the phase spectrum difference between two independent pulses from their Hong-Ou-Mandel interference pattern and intensity spectra. Our confirmatory experiment with coherent state pulses confirms the accuracy of the recovered phase spectrum difference to within plus or minus 0.1 rad. The method we employ is readily generalizable to the measurement of single-photon wave packets and even correlated photon pairs.

  We investigate the precision of estimating the interaction strength between a two-level system and a single-photon pulse when the latter is subject to chirping. We show that experimentally feasible measurements are optimal, or close to it, for chirped, pulsed single photon spectroscopy.

  We experimentally demonstrate a spectroscopic super-resolution method aimed at broadband light (10s to 100s of GHz) We study the paradigmatic problem of estimating a small separation between two incoherent spectral features of equal brightness, with a small number of photons per coherence time. The setup is based on an actively stabilized Mach-Zehnder-type interferometer with electro-optic time lenses and passive spectral dispersers implementing the inversion.

  We have developed a theory of parametric photon generation in the waveguides coupled to arrays of quantum emitters with temporally modulated resonance frequencies. Such generation can be interpreted as a dynamical Casimir effect. We demonstrate numerically and analytically how the emission directionality and photon-photon correlations can be controlled by the phases of the modulation.

  We study a system of two interacting, non-indentical quantum emitters driven by a coherent field. We show that the features imprinted by the two-photon dynamics into the spectrum of resonance fluorescence are particularly sensitive to changes in the distance between emitters. This can be exploited for applications such as superresolution imaging of point-like sources.

• Observing coherences with time-resolved photoemission [77.34726150561087]
  We discuss the potential creation and measurement of coherences in both dispersive solids and qubit-like single levels using current generation time- and angle-resolved photoemission technology. We show that in both cases, when both the pump and the probe overlap energetically with the coherent levels, that the time-resolved photoemission signal shows a beating pattern at the energy difference between the levels. In the case of dispersive bands, this leads to momentum-dependent oscillations, which may be used to map out small energy scales in the band structure.
