Quantum and ghost imaging
Quantum Imaging:
The objective is to develop a new technique for remote imaging using correlations between two entangled harmonic photons from the same fiber laser source. We will particularly investigate the possibility of instantaneously transferring spatial information from an ‘object’ point to an ‘image’ point in free space, either in the far-field regime (Far Field Quantum Imaging) or in the near-field regime (Quantum Diffractive Imaging).
Figure 8: The entangled harmonic source can be used in an interferometric setup (left) or in a diffractive regime (right).
X-ray Photon Correlation Imaging (GHOST Imaging)
The NANOX SCAN project is a European initiative aimed at developing a correlated X-ray microscope (GHOST Imaging) to image viruses and viral structures for the first time. The work focuses particularly on the generation of X-rays. These will be generated by focusing a femtosecond laser on a jet of metallic nanoparticles or a liquid jet of rare gas (Ar, Kr). The study of X-ray photon correlations, and even entanglement, will be applied to biological imaging techniques with extreme resolutions approaching Heisenberg’s limit.
