3D Quantum Ghost Imaging

We present current results of a novel type of setup for quantum ghost imaging based on asynchronous single-photon timing using SPAD detectors, first presented in [1]. The scheme enables photon pairing without fixed delays and thus overcomes some limitations of the widely used heralded setups for quantum ghost imaging [2]. It especially allows 3-dimensional imaging by direct Time of Flight methods, the first demonstration of which will be shown here. To our knowledge it is also the first demonstration of 3-dimensional Quantum Ghost Imaging at all.
