Quantum Entanglement Imaged

A team of scientists from Glagow University have produced the first ever full-field coincidence images of a phase object probed by photons from an entagled pair source.

The team led by Paul-Antoine Moreau from the School of Physics and Astronomy at Glasgow University used a stream of photons from an entangled pair source fired at non-conventional objects - displayed on liquid crystal materials which change the phase of photons that pass through.

The image exhibits a violation of a Bell inequality with S = 2.44 +/- 0.04

Paul-Antoine Moreau, of the University of Glasgow's School of Physics and Astronomy, said:
"The image we've managed to capture is an elegant demonstration of a fundamental property of nature, seen for the very first time in the form of an image.

"It's an exciting result which could be used to advance the emerging field of quantum computing and lead to new types of imaging."
