Scottish Heads Take for the First Time a Quantum Entanglement • The Register

Peak Physicists from the University of Glasgow, Scotland, have produced the very first image of a solid form of quantum entanglement, called Bell entanglement.

To do this, they have developed a system that triggers a stream of entangled photons from a quantum light source on "unconventional objects" – which alter the phase of the photons as they pass.

The researchers then set up a super sensitive camera capable of detecting single photons that would only take an image if it sighted both the photon and its entangled "twin", thus creating a visible record of entanglement.

Ladies and gentlemen, here's what Bell's entanglement looks like:

Quantum entanglement has been described by Albert Einstein as "a phantasmagorical action at a distance". In this process, two or more particles may have certain physical properties, and the change to one particle will immediately change the properties of the other, even if they are separated by hundreds of kilometers.

Quantum entanglement should not be possible and this is one of the reasons why scientists find it so difficult to reconcile Einstein's theory of general relativity with quantum mechanics.

The particular type of entanglement studied in the experiment, Bell's entanglement, takes its name from John Stewart Bell, author of Bell's theorem, which excludes local hidden variables as a viable explanation of quantum mechanics.

Bell formalized the concept of quantum entanglement and significantly criticized Einstein's principle of local realism – both hypothesizing that nothing can go faster than the speed of light and the assumption that a particle must objectively have a pre-existing value to be measured.

The results of the Glasgow experiment were published Friday in the journal Science Advances.

"The image we managed to capture is an elegant demonstration of a fundamental property of nature, seen for the very first time in the form of an image," said Dr. Paul- Antoine Moreau from the School of Physics and Astronomy at the University of Glasgow. and lead author of the document.

"This is an exciting result that could be used to advance the emerging field of quantum computing and lead to new types of imaging."

In the future, quantum entanglement could be used to send coded information in qubits – quantum information base units that can transmit one, zero, or both at a time – to create clusters. Quantum computers, with a greatly increased computing capacity. ®
