style="font-size:12.0pt;font-family:"Times New
Roman","serif";color:black">Compressive sensing
utilizes sparsity to realize efficient image reconstruction.
It is a valuable processing technique when cost, power,
technology or computational overhead are limited or high. In
the quantum domain technology usually limits efficient
acquisition of weak or fragile signals. We have used
compressive sampling for low-flux laser Radar [1], photonic
phase transitions, high resolution biphoton ghost imaging [2],
Ghost object tracking [3] and high dimensional entanglement
characterization [4]. As shown below, we were able to
efficiently and rapidly reconstruct high dimensional joint
probability functions of biphotons in momentum and position.
With conventional raster scanning this process would take
approximately a year, but using double-pixel compressive
sensing, the pictures were acquired in a few hours with modest
flux. </span><o:p></o:p></p>
