Scientists Have Uncovered The First Ever Image Of Quantum Entanglement

British physicists have captured the first images of a quantum entanglement, capturing visual evidence of the elusive phenomenon, in research that could boost fields such as quantum computing.


In quantum mechanics, two interacting particles, such as two photons passing through a beam splitter, can be “entangled” in a very strange way, sharing their physical state instantaneously, no matter how far apart they are. This connection, called quantum entanglement, is one of the fundamental phenomena in the field of quantum mechanics, and Einstein once called it “ghostly action at a distance.”

Today, quantum entanglement has never been captured in a single image, although it is useful in practical applications such as quantum computing and cryptography. In the latest study, physicists at the university of Glasgow set up a complex experiment to capture quantum entanglement in an image.


The researchers designed a system that emits a bundle of entangled photons from a quantum light source toward the “unconventional” material shown on the liquid crystal material, which changes the phase of the photons as they pass through.

They placed an ultra-sensitive camera capable of detecting individual photons. When the photon is seen with its entangled twin, the camera captures the first precious image of the photon entanglement, always showing the two photons seemingly reflecting off each other to form a ring shape.


Paper first author, Glasgow university institute of physics and astronomy Dr Paul Anthony morrow said: “this image is a basic property of natural elegance, quantum entanglement in the form of images were seen for the first time, the results can promote the development of quantum computing emerging field, and gave rise to new imaging techniques and equipment.”
