The production of pairs of entangled photons simply by focusing a laser beam onto a crystal
with a nonlinear optical response was used to test quantum mechanics and to open new …

Cerenkov luminescence imaging (CLI) is a novel imaging modality to study charged
particles with optical methods by detecting the Cerenkov luminescence produced in tissue …

The light produced by parametric down-conversion shows strong spatial entanglement that
leads to violations of EPR criteria for separability. Historically, such studies have been …

We introduce a novel time-frequency quantum key distribution (TFQKD) scheme based on
photon pairs entangled in these two conjugate degrees of freedom. The scheme uses …

Correlated photon imaging, popularly known as ghost imaging, is a technique whereby an
image is formed from light that has never interacted with the object. In ghost imaging …

Electron multiplication charge-coupled devices (EMCCD) are widely used for photon
counting experiments and measurements of low intensity light sources, and are extensively …

Quantum imaging and microscopy profit from quantum correlations and entanglement to
image objects and samples with resolution and sensitivity that goes far beyond what can be …

Cameras with single-photon sensitivities can be used to measure the spatial correlations
between the photon-pairs that are produced by parametric down-conversion. Even when …

Cells emit light at ultra-low intensities: photons which are produced as by-products of
cellular metabolism, distinct from other light emission processes such as delayed …

Commercially available cameras do not have a low-enough dark noise to directly capture
double-slit interference at the single photon level. In this work, camera noise levels are …
