We present images made by off-axes quantum holography (OAQH) and discuss image capabilities of the system. In this work we use a pair of quantum correlated photons, generated by spontaneous parametric down-conversion in a non-linear crystal; one photon form a pair interacts with object, and another is detected. In our system both photons are in near infra-red, but by slight modifications they will be in different spectral regions, interacting photons in mid infra-red, detected photons in visible or near infra-ed. This opens very useful applications of QIUP for imaging and sensing in MIR.enParametric photon down conversionQuantum correlated photon pairsQuantum imagingconference paper
