We present first results of a novel type of setup for quantum ghost imaging based on asynchronous single photon timing using single photon avalanche diode (SPAD) detectors. This scheme enables photon pairing with arbitrary path length difference and does, therefore, obviate the dependence on optical delay lines of current quantum ghost imaging setups [ Nat. Commun. 6 , 5913 ( 2015 ) NCAOBW 2041-1723 10.1038/ncomms6913 ]. It is also, to our knowledge, the first quantum ghost imaging setup to allow three-dimensional imaging.
