Query: Ray-tracing with quantum correlated photons to image a 3D scene   To capture the 3D information of a scene, conventional techniques often
require multiple 2D images of the scene to be captured from different
perspectives. In this work we demonstrate the reconstruction of a scene's 3D
information through ray-tracing using quantum correlated photon pairs. By
capturing the two photons in different image planes using time-tagging cameras
and taking advantage of the position, momentum and time correlation of the
photons, the photons' propagation trajectory can be reconstructed. With this
information on every photon pair, we were able to demonstrate refocusing, depth
of field adjustment and parallax visualization of a 3D scene. With future
camera advancements, this technique could achieve a much higher momentum
resolution than conventional techniques thus giving larger depth of field and
more viewing angles. The high photon correlation and low photon flux from a
quantum source also makes the technique well suited for 3D imaging of light
sensitive samples.
