• Abstract: Temporal ghost imaging is based on the temporal correlations of two optical beams and aims at forming a temporal image of a temporal object with a resolution, fundamentally limited by the photodetector resolution time and reaching 55 ps in a recent experiment. For further improvement of the temporal resolution, it is suggested to form a spatial ghost image of a temporal object relying on strong temporal-spatial correlations of two optical beams. Such correlations are known to exist between two entangled beams generated in type-I parametric downconversion. It is shown that a sub-picosecond-scale temporal resolution is accessible with a realistic source of entangled photons.

  We study a possibility of measuring the time-resolved second-order autocorrelation function of one of two beams generated in type-II parametricconversion. We show that such a measurement enables one to infer directly the degree of global coherence of that beam. Our theoretical model also shows that the magnified double-heralded autocorrelation function of one beam exhibits a local maximum around zero delay time.

  We analytically study the interference of two photons with different temporal shapes through a beam splitter (BS) We find that maximum mode entanglement can be achieved with a 50/50 BS configuration. The temporal entanglement and shaping of photons based on interference may solve the shape mismatch issues in large-scale optical quantum networks.

  correlation of the-dimensional-temporal correlations of light provides an interesting tool to overcome the traditional limitations of standard imaging. Using plenoptic imaging, one can detect both the spatial distribution and direction of light in a scene, pushing both resolution and depth of field to the fundamental limit imposed by wave-optics.

We find that the visibility for two photons emitted from a three-level system (3LS) in ladder configuration can be enhanced significantly for a wide range of parameters by slowing down the decay of the upper level of the 3LS.

  Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols. Here, we demonstrate a functional source of high-dimensional, noise-resilient hyperentangled states encoded in time-frequency and vector-vortex structured modes. We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.

• 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.
