First image of Einstein's 'spooky' particle entanglement
Einstein described quantum mechanics as "spooky" because of the instantaneousness of the apparent remote interaction between two entangled particles.
The interaction also seemed incompatible with elements of his special theory of relativity.
The photo shows a strong form of quantum entanglement, where two particles interact and share their physical states for an instant.
It occurs no matter how great the distance between the particles is.
The connection is known as Bell entanglement and underpins the field of quantum mechanics.
Paul-Antoine Moreau, of the University of Glasgow's School of Physics and Astronomy, said the image was "an elegant demonstration of a fundamental property of nature".
He added: "It's an exciting result which could be used to advance the emerging field of quantum computing and lead to new types of imaging."
