Abstract

Here we report on the first realisation of ghost imaging of a macroscopic object using massive particles. The correlated pairs of ultracold metastable helium atoms are originating from two colliding Bose-Einstein condensates (BECs). We use higher-order Kapitza-Dirac scattering to generate the large number of correlated atom pairs required, enabling the creation of a ghost image with good visibility and sub-millimetre resolution. Future extensions could include ghost interference and EPR tests [1].
