Scientists have for the first time, shot a picture of a phenomenon that Albert Einstein once described as a "ghostly action from a distance".

The image is a strong form of quantum entanglement, where two particles interact with each other and share their physical states for an instant – no matter how far apart they are.

This connection is known as Bell's entanglement and is the basis of quantum mechanics.

Paul-Antoine Moro, of the University of Glasgow School of Physics and Astronomy, said: "The image we captured is an elegant demonstration of the fundamental property of nature that is first seen in the form of an image. , This is an exciting result that can be used to develop the emerging field of quantum computing and lead to new types of imagery. "

Einstein believed that quantum mechanics was "ghostly" because of the momentum of the apparent remote interaction between two entangled particles. This seemed incompatible with the elements of his special theory of relativity.

Scientist John Bell later formalized this concept, describing a strong form of tangle showing this characteristic. Bell's entanglement today is used in practical applications such as quantum computation and cryptography. However, it has never been photographed so far in one image.

The Glasgow University Physics Team describes how to capture the phenomenon for the first time in a photo.

They invented a system that fired a stream of confused photons from the quantum light source into "unconventional" objects – exposed to liquid-crystal materials that change the phase of the photons as they pass.
