Scientists unveiled the first ever captured photograph of quantum entanglement, the physical phenomenon in which two or more "entangled" particles are connected via their quantum states, even over large distances.
Physicists at Glasglow University have published the picture and a report of their findings in the journal Scientists progress in an article entitled "Imaging Bell-type type behavior".
The groundbreaking photo shows two entangled photons sharing physical states for a brief moment in a strong form of quantum entanglement called Bell entanglement.
To create the photo, scientists pumped a beta-barium borate crystal (BBO) with an ultraviolet laser, which produces quantum-bound photons. This entangled photon flux was then separated with a beam splitter and the first photon was sent through objects that change the phase of the photons passing through it.
An ultra-sensitive camera was triggered to capture photos of the two entangled "twins" photons, thus producing the image of quantum entanglement.
Scientists say this pioneering photo opens the door to "a whole new class of quantum imaging demonstrations and techniques."
