During the 1930's, the famous physicist Albert Einstein returned to the field of quantum mechanics, assisted by his theory of relativity to create. Hoping to develop a more complete theory of how the particles move, Einstein instead horrified the prospect of the whole contradiction – something he described as "scary action in a distance".
Despite Einstein's misgivings, the total disruption has become a part of the mechanics of the whole. And now, for the first time, a team of physicists from the University of Glasgow took an image of a form of quantum entanglement (aka Bell drain) at work. In doing so, they got the first piece of visual evidence an unusual thing that was confused even by Einstein himself.
The paper described in their findings, entitled "Imaging Bell-type nonlocal behavior", recently appeared in the journal Science Development . The study was led by Dr. Paul-Antoine Moreau, a Leverhulme Early Career Fellow at the University of Glasgow, and has included many researchers from Glasgow's School of Physics & Astronomy.
Quantum entanglement illustrates the phenomenon in which the two particles that interact with each other can remain connected, instantly sharing their physical states no matter how far they are. This connection is in the center of quantum mechanics, even when it violates the concept of local realism and many elements of Special Relativity.
By 1964, Sir John Bell expanded the work of former theories through the formal concept of non-interaction and describing a strong form of marriage. It is known as Bell entanglement, a concept used for many scientific applications – such as quantum computing and cryptography.
However, until now, it has not got an image. As Dr. said. Moreau at a press release by the University of Glasgow:
"The image we capture to capture is an elegant display of a major property of nature, seen for the first time in the form of an image. exciting results that can be used to advance the emerging field of quantum computing and lead to new types of imaging. "
For the sake of their study, the research team built a system if where a stream of misunderstood images is cut off from the source of the sum of light. This stream then passes through a series of "unusual", which refers to the liquid-crystal materials that change the part of the photons as they pass.
Setup also includes a super-sensitive camera with the ability to see single photons and capture pictures of them. However, the camera has been programmed to take only pictures when it captures the sight of both a photon and twin twins. In doing so, the experiment is effective to create a visible record of the interference of two photons.
The results of this study open the door to a whole new world of quantum-source strategies that take advantage of Bell belles. It also has implications in the field of quantum information (ie quantum computing and cryptology)
