Towards Quantum 3D Imaging Devices

We review the advancement of research toward design and implementation quantum plenoptic cameras, radically novel 3D imaging devices that exploit both momentum–position entanglement photon–number correlations to provide typical refocusing ultra-fast, scanning-free, capability devices, along with dramatically enhanced performances, unattainable in standard cameras: diffraction-limited resolution, large depth focus, ultra-low noise. To further increase volumetric resolution beyond Rayleigh diffraction limit, achieve we are also developing dedicated protocols based on Fisher information. However, for advantages proposed be effective appealing end-users, two main challenges need tackled. First, due number frames required correlation measurements an acceptable signal-to-noise ratio, (QPI) would require, if implemented commercially available high-resolution acquisition times ranging from tens seconds a few minutes. Second, elaboration this amount data, order retrieve images or 2D images, requires high-performance time-consuming computation. address these challenges, single-photon avalanche photodiode (SPAD) arrays low-level programming ultra-fast electronics, combined compressive sensing tomography algorithms, aim reduce time by orders magnitude. Routes exploitation QPI will discussed.
