• Abstract: The observation of the Hong-Ou-Mandel (HOM)-type two-photon interference (TPI) has played an important role in the development of photonic quantum technologies. The time-resolved coincidence-detection technique has been effectively used to identify and characterize the TPI phenomena of long-coherence optical fields. Here, we report on the experimental demonstration of the TPI of two phase-randomized weak coherent pulses with time-resolved coincidence detection. The mutual coherence time between the two weak coherent lights is determined by applying a frequency noise to one of the two interfering lights. We analyze the HOM-type TPI-fringe visibility according to the ratio of the coherence time to the pulse duration.

  We show that time-asymmetries in the cross-correlations of photons corresponding to different polarizations can be exploited to probe quantum coherent transport mechanisms and steady-state coherence properties. Our results put forward photon correlation asymmetry as a promising approach to investigate coherent contributions to excited-stated dynamics in molecular aggregates and other many-site quantum emitters.

  Multiphoton interference is an important phenomenon in modern quantum mechanics and experimental quantum optics. Recently, the two-photon interference (TPI) of phase-randomized weak coherent states has played a key role in the realization of long-distance quantum communication. We experimentally examined the Hong-Ou-Mandel-type TPI of phase-randomized weak coherent pulses to compare the TPI effect with that of correlated photons.

• Distinguishability and "which pathway" information in multidimensional interferometric spectroscopy with a single entangled photon-pair [0.0]
  Photon exchange-phase and degree of distinguishability have not been widely utilized in quantum-enhanced applications. We show that even at low degree entanglement, when a two-photon wave-function is coupled to matter, it is encoded with a reliable "which pathway?" information. We find that quantum-light interferometry facilitates utterly different set of time-delay variables, which are unbound by uncertainty to the inverse bandwidth of the wave-packet.

  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.

We also show that phase correlations in the JSA spectral intensity correlations between two signal photons, even when the corresponding idler photons are not detected, link this correlation pattern to the purity of a single signal photon.

• 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.

  In spite of particle losses the quantum entanglement propagation exhibits a ballistic character with propagation speeds related to the differerent quasiparticles that are involved in the dynamics. Our analysis reveals that photon dissipation has a strikingly asymmetric behavior in the two configurations with a much more dramatic role on the holon entanglement propagation than for the doublon case.
