The 3D quantum ghost imaging microscope setup. A laser and crystal (left) are used to make entangled photons, which are split and sent in two directions. One turns left to hit and scatter off a sample, providing a standard image at a 90-degree angle. The other continues straight and is used to construct a ghost image. (Credit: Eshun et al.)

Abstract
Quantum ghost imaging uses quantum-entangled photons to generate a two-dimensional image with only a bucket detector at the sample. Here we expand on this approach to generate a three-dimensional image without scanning. A quantum-entangled light source directly links information between a pair of 2D sensors, one of which captures a standard image from one perspective and a second sensor which captures a ghost image from a perpendicular perspective. By correlating the spatial information from the two detectors for each photon pair, we obtain three dimensions of spatial information (x,y , and z ) for each scattered photon. We demonstrate that this system can study microscopic environments by imaging scattering from metallic nanoparticle clusters. This approach has the potential to greatly reduce the flux of light required to obtain a 3D image of a biological sample and thereby extend the number of images that can be obtained before photodamaging the sample.
