People have different ideas about ghosts. Someone refuses to believe in their existence, someone represents exactly how they are drawn by books and mystical films, and someone believes that ghosts can be felt and seen.
Quantum cameras rush to the rescue
The great physicist Albert Einstein at one time tried to prove the theory of the existence of ghosts. However, unfortunately, he did not have the technical equipment that modern scientists have. Now the ghost shell can be "caught" on film using a quantum camera.
Just to begin with, we need to clarify the situation: photographs cannot capture the wandering souls of deceased ancestors. Rather, they display an image of photons that are not visible in the lens of a conventional digital camera.

The result of quantum entanglement
Sometimes, foreign objects are visible in the pictures, which are not the result of poor quality printing. The fact is that sometimes a conventional camera can capture objects that are not immediately visible through the lens. It is difficult to get an image of a phantom, because light is not refracted through it. However, such a phenomenon as quantum entanglement can help in this matter. In this quantum-mechanical phenomenon, two or more objects retain their interdependence for some time. And this happens regardless of how far away they are from each other.
For example, you can always get such a pair of photons, one of which has a positive spin (rotation of elementary particles), and the other negative. In other words, there is always another photon with positive spinality. Measurements made in the same system directly affect and intertwine with other systems. However, no one still knows how it works.
How to capture a phantom on film?
The quantum chambers are equipped with two separate laser beams with entangled photons. And if one ray of the lens is directed at the picture, then the other recreates connections that are not visible to the lens. According to experts, this is a very smart decision. In a sense, this is magic, born through quantum optics. Paul Lett, an expert at the National Institute of Standards and Technology in Gaithersburg, Maryland, says: “Everything that we see now is not a new word in physics. This is a neat demonstration of physical capabilities in practice."
Actual experiment
As you might have guessed, the actual experiment was performed with a quantum camera. His results were published in the journal Nature. To do this, the researchers used tiny cat stencils and a trident engraved in silicon. It was recorded that two beams of light passed through the holes at different wavelengths. As a result, the first and second rays got entangled, but one of them missed the target, but continued to travel on the other line.
Conclusion
A truly surprising result is that the second light beam also participated in the formation of objects in the image at the time when the camera was focused on it. This is despite the fact that it has never refracted through any of the objects. According to the expert, this is a long-standing experimental idea that can lead to something in practice. For example, in a medical imaging setting.
