  As an important imaging technique, holography has been realized with
different physical dimensions of light,including polarization, wavelength, and
time. Recently, quantum holography has been realized by utilizing polarization
entangled state with the advantages of high robustness and enhanced spatial
resolution, comparing with classical one. However, the polarization is only a
two-dimensional degree of freedom, which greatly limits the capacity of quantum
holography. Here, we propose a method to realize high-dimensional quantum
holography by using high-dimensional orbital angular momentum (OAM)
entanglement. A high capacity OAM-encoded quantum holographic system can be
obtained by multiplexing a wide range of OAM-dependent holographic images.
Proof-of-principle experiments with four- and six-dimensional OAM entangled
states have been implemented and verify the feasibility of our idea. Our
experimental results also demonstrate that the high-dimensional quantum
holography shows a high robustness to classical noise. Furthermore,
OAMselective holographic scheme for quantum encryption is proposed and
demonstrated. Comparing with the previous schemes, the level of security of
holographic imaging encryption system can be greatly improved in our
high-dimensional quantum holography.
