First picture of photons in quantum entanglement

Strong quantum entanglement was first described by British physicist Sir John Bell in 1964, but it remained until July 2019 before scientists took the first picture of photons of light in full quantum entanglement (QE). QE is a strange property of particles, such as photons of light, to be in apparent communication with each other over large distances. Albert Einstein called this phenomenon as 'spooky' though it now forms the basis for quantum computing and quantum communications, both emerging engineering realities. So, in July 2019, scientists from the University of Glasgow, Scotland, UK, used a super-sensitive camera to capture pairs of photons in this unique aspect of nature. A UV Laser was used to illuminate a crystal which split photons of light from each other and the resulting image captured by the photon counting camera.
