Scientists create the & # 39; first image & # 39; for the camera of quantum entanglement that Einstein ever & # 39; ghostly remote action & # 39; called
- Physicists from the University of Glasgow have documented the phenomenon
- This is where two particles interact and share their physical states
- This connection is impossible under the rules that govern the wider universe
- That's because the particles interact for a moment, regardless of their distance
For the first time, physicists have captured an image of quantum entanglement that a bewildered Albert Einstein once & # 39; ghostly remote action & # 39; called.
Researchers say they have obtained visual evidence of a strong form of the elusive phenomenon of Bell entanglement.
Quantum entanglement is where two particles interact and share their physical state for a moment – no matter how large the distance separates them.
This connection, despite being impossible under the rules that govern the wider universe, supports the field of quantum mechanics.
This is the branch of scientific research that tries to explain and set rules for the way in which particles smaller than the atom behave.

A team of physicists from the University of Glasgow described how they first photographed the phenomenon.
They developed a system that fires a stream of entangled photons from a quantum source of light at & # 39; non-conventional & # 39; objects – displayed on liquid crystal materials that change the phase of the photons as they pass.
& # 39; The image we have captured is an elegant demonstration of a fundamental characteristic of nature, first seen in the form of an image, & # 39; said Paul-Antoine Moreau of the physics and astronomy school of the university.
& # 39; It is an exciting result that can be used to promote the emerging field of quantum computing and to lead to new forms of imaging. & # 39;
Einstein thought quantum mechanics & # 39; spooky & # 39; was due to the instantaneous nature of the apparent distance interaction between two entangled particles.
This seemed incompatible with elements of his special theory of relativity.
Scientist Sir John Bell later formalized this concept by describing a strong form of entanglement that has this function.
Bell entanglement is used today in practical applications such as quantum computing and cryptography, but it has never been captured in a single image.

One area where these developments are being deployed is in the area of quantum internet.
British scientists reported in November 2018 that they had made an important breakthrough in the pursuit of an ultra-fast and hyper-secure quantum internet.
A quantum computer could perform calculations that would cost the current supercomputers billions of years to perform.
It would also allow the creation of irrevocable digital connections, help find remedies for dementia, create new medicines, and develop more efficient fertilizers.
Experts claim to tame & # 39; tame & # 39; one of the major problems that plagued the development of the field.
Quantum entanglement is very sensitive to environmental influences that can easily disrupt a signal.
But the researchers at Sussex University believe that microwave technology can be used to isolate the devices and protect them from this problem.
The full findings of the new study were published in the journal Science Advance.
WHAT IS QUANTUM ENTLELEMENT?
In quantum physics entangled particles remain connected, so that actions performed by one influence the behavior of the other, even if they are separated from each other by enormous distances.
This means that if you measure, & # 39; up & # 39; for the spin of one photon from a confused pair, the rotation of the other, measured a moment later, & # 39; down & # 39; – even if the two are on either side of the world.
Entanglement occurs when a part of the particles interacts physically.

A laser beam fired by, for example, a certain type of crystal can cause individual light particles to be split into pairs of entangled photons.
The theory that so confused Einstein is also called & # 39; ghostly remote action & # 39; called.
Einstein was not happy with the theory, because it suggested that information could travel faster than light.
