• Abstract: Conventional optical imaging is limited by diffraction, preventing discrimination of closely spaced incoherent sources. Inspired by quantum parameter estimation, this thesis explores spatial-mode demultiplexing (SPADE) as a method to overcome this limit by projecting light onto an orthonormal mode basis. In this work, we design and experimentally validate a practical implementation of spatial-mode demultiplexing via Multi-Plane Light Conversion (MPLC).

• Super-resolution of ultrafast pulses via spectral inversion [0.0]
  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.

  Most fusion methods solely focus on the fusion algorithm itself and overlook the degradation models. We propose physics-inspired degradation models (PIDM) to model the degradation of LR-HSI and HR-MSI. Our proposed PIDM can boost the fusion performance of existing fusion methods in practical scenarios.

  We investigate the application of genetic and machine learning approaches to tomographic problems. We find that the neural network-based scheme provides a significant speed-up, that may be critical in applications requiring a characterization in real-time. We expect these results to lay the groundwork for the optimization of tomographic approaches in more general quantum processes.

  We study the spectral dependence of the transverse Laguerre-Gauss modes in parametric downconversion. We show how the spectral and spatial coupling can be harnessed to tune the purity of the well-known orbital angular momentum entanglement. This work has implications for efficient collection of entangled photons in a transverse single mode, quantum imaging, and engineering pure states for high-dimensional quantum information processing.

• A theoretical framework for photon-subtraction with non-mode selective resources [0.0]
  This work explicitly describes single-photon subtraction from multimode quantum light in the context of non-Gaussian state generation and manipulation. The obtained theoretical framework allows retrieving, given a multimode input state, optimal conditions required to herald and then to detect non-Gaussian states. The application of the proposed approach to the case study of Schr"odinger kitten preparation starting from a frequency multimode squeezed state illustrates the impact of the derived theoretical tools.

• Fast Generation and Detection of Spatial Modes of Light using an Acousto-Optic Modulator [62.997667081978825]
  spatial modes of light provide a high-dimensional space that can be used to encode both classical and quantum information. Current approaches for dynamically generating and measuring these modes are slow, due to the need to reconfigure a high-resolution phase mask. We experimentally realize this approach, using a double-pass AOM to generate one of five orbital angular momentum states. We are able to reconstruct arbitrary states in under 1 ms with an average fidelity of 96.9%.
