Andor iXon Ultra EMCCD imaging cameras are used to superb effect in systems where spatially correlated biphotons, one or two pixels apart, need to be detected with superb levels of discrimination and confidence, ultimately yielding accelerated measurement throughout.
Key iXon Benefits:
Ghost Imaging is a technique whereby an image is formed from light that has never interacted with the object. In ghost imaging experiments, two correlated light fields are produced. One of these fields illuminates the object, and the other field is measured by a spatially resolving detector.
Andor Intensified Cameras are used in such heralding detection systems, providing time-gated detection of single photon events across the full scene, avoiding the need to scan single pixel detectors and offering a dramatic increase in efficiency in the measurement of high-dimensional spatial entanglement.
Key Intensified Camera Benefits:
"Parametric Down-Conversion (PDC) is central to most experiments in quantum optics. In essence, photons from an incident pump beam are absorbed by a non-linear crystal and two new photons are created. These new photons are created in exactly the same position and with exactly opposite transverse momentum."

Entangled states of light are essential for quantum technologies and fundamental tests of physics. Current systems rely on entanglement in 2D degrees of freedom, e.g., polarization states. Increasing the dimensionality provides exponential speed-up of quantum computation, enhances the channel capacity and security of quantum communication protocols, and enables quantum imaging; unfortunately, characterizing high-dimensional entanglement of even bipartite quantum states remains prohibitively time-consuming.
In this work, Reichert, Defienne and Fleisher, Princeton University, have used an Andor iXon Ultra EMCCD to develop and experimentally demonstrate a new theory of camera detection that leverages the massive parallelization inherent in an array of pixels. It is shown that a megapixel EMCCD array could measure a joint Hilbert space of 1012 dimensions, with a speed-up of nearly four orders-of-magnitude over traditional methods.
