The first ever picture of quantum entanglement
Source:Physicists from the Scottish University of Glasgow reported an experiment in which scientists were able to get the first ever photograph of the particles. Phenomena by the standards of physics are so strange that even the great scientist of 20th century albert Einstein called it "spooky action at a distance". The achievement of Scottish scientists is very important for the development of new technologies. Why? Let's deal.
What is quantum entanglement?
If we talk in simple words, quantum entanglement is a phenomenon in which the States of two or more objects, usually of particles, may be interdependent, regardless of their distance from each other. In other words, even if you alienate these particles for many thousands of kilometers from each other – each of them will change its state in accordance with the change of state of the other particle. Such particles are called entangled and the phenomenon of quantum entanglement.
Although the very concept of quantum entanglement was proposed in the beginning of the 20th century albert Einstein, the mathematical method of proof that particles can be entangled to each other, was proposed a few decades after him, the Irish physicist John bell. This method is called "". If the definition of quantum entanglement, these inequalities have no solutions, it proves the presence of entanglement.
How they were obtained the first picture of quantum entanglement?
Physicists from the Scottish University of Glasgow have found a way to visualize these inequalities, having received the first photographic evidence of quantum entanglement. For this, they have created a very light sensitive camera that responds to flows of entangled photons, producing special light source.
a diagram of the experimental system looks like this: crystal in the lower left corner creates a bunch of pairs of entangled photons, which then splits into two. One passes through special filters and then hits the detector. The second beam directly hits the detector.
The Installation creates a completely the same in terms of properties of pairs of photons. Then they are separated. One photon passes through filters that alter its physical properties (condition a). The other photon goes directly to a special detector, bypassing the filters. Light-sensitive camera was set up in such a way to capture when both photons had changed his physical condition, even separated by distance.
a Pair of entangled photons in which one of them changed its status in accordance with the changing state of the other photon
Observations have shown that the photons that passed through the filters and those using them were the same to change their status. In the experiment, the scientists obtained four photographs of altered States of photons, and one picture showing the pair of photons in which one photon passed through the filters, the other does not. This observation was the first visual evidence of the phenomenon of quantum entanglement.
Why?
The results of the research by Scottish scientists can push the development of technologies for observing quantum phenomena. The ability to monitor these processes will bring researchers to fully understand them and their practical use.
