  Hyperspectral imaging (HSI) has a wide range of applications from
environmental monitoring to biotechnology. Current snapshot HSI techniques all
require a trade-off between spatial and spectral resolution and are thus unable
to achieve high resolutions in both simultaneously. Additionally, the
techniques are resource inefficient with most of the photons lost through
spectral filtering. Here, we demonstrate a snapshot HSI technique utilizing the
strong spectro-temporal correlations inherent in entangled photons using a
modified quantum ghost spectroscopy system, where the target is directly imaged
with one photon and the spectral information gained through ghost spectroscopy
from the partner photon. As only a few rows of pixels near the edge of the
camera are used for the spectrometer, almost no spatial resolution is
sacrificed for spectral. Also since no spectral filtering is required, all
photons contribute to the HSI process making the technique much more resource
efficient.
