Fast cameras for imaging entanglement

Quantum entanglement is now being studied with the aim of providing insight into the practical applications of this phenomenon. Quantum cryptography, communication and computing may soon rely on high-fidelity readouts of entangled photons. To detect these single particles researchers must rely on the most sensitive detectors including EMCCD and intensified sCMOS cameras.

Miles Padgett

"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."

Dr Miles Padgett, Professor of Optics, University of Glasgow

Single photon holography

Until quite recently, creating a hologram of a single photon was believed to be impossible due to fundamental laws of physics. However, scientists at the Faculty of Physics, University of Warsaw, have successfully applied concepts of classical holography to the world of quantum phenomena. A new measurement technique has enabled them to register the first ever hologram of a single light particle, thereby shedding new light on the foundations of quantum mechanics.

Quantum imaging saves Schrödinger's cat

For the first time, a team of scientists, with a novel experiment using an Andor electron-multiplying CCD (EMCCD) camera, have demonstrated quantum imaging with tangible impact for other imaging applications. In the elegant experiment they have improved on the previous ghost imaging and interaction-free imaging approaches by both proving the occurrence of quantum imaging and demonstrating the potential for future applications of this technique.

Time-resolved imaging of the Laguerre-Gauss modes

Quantum entanglement occurs when two particles remain connected, even over large distances, so that actions performed on one particle have an effect on the other. Einstein described photon entanglement as "Spooky action at a distance”. Quantum entanglement understanding is the basis of the growing fields of quantum computing and quantum cryptography.
