Twist in the famous famous experience deals with a kick of Einstein’s quantum doubts

Albert Einstein did not hate understanding the famous quantum theory that material things, including light, exist as a particle and a wave, and that this duality cannot be observed simultaneously. But the simple new repetition of the founding quantum experience provides the most cruel and direct evidence so far that Einstein may have been wrong.

In a modern paper for Physical review messagesThe Massachusetts Institute of Technology has repeated the atomic dual experience, allowing an unprecedented level of experimental accuracy. By using Supercold atoms as “cracks” to pass light, the team confirmed that the wave particles of light-with all its contrasting properties-are even in basic quantum standards.

the Double experienceBy the British physicist Thomas Young for the first time in 1801, explains the dual nature of light in the quantum world. When a ray of light shines – “particles”, Foton, after a direct path – through two parallel lubites on the screen, what appears on the other side is a looked overlap pattern in a pond, such as “wave”. But if you try to pick up this mysterious transition at work by looking at the fissure, you lose the intervention pattern.

In this discussion, Nilz Bohr, Nils Bohr, pointed out this result as a result integrationThe idea that it is impossible to measure the supplementary characteristics of the quantum system at the same time. But Einstein pretended that if a paper incision was hit in its place in the spring, the individual photons will shake the spring in a particle -like way. This way, we are Be able to Adherence to the duplicity of light at work.

To test this hypothesis, the Massachusetts Institute Technology team stripped its experimental preparation to the single atomic scale, which cools it to Microkelvin temperatures (for context, equivalent to one -460 ° F -Fahrenheit or -272 ° C). Use the laser to arrange more than 10,000 atoms in an elegant crystal composition. This highly controlled environment allowed researchers to control the “ambiguity” of each atom, or a certainty of its location. Simply put, the foggy corn increases the possibility of the photon through which a particle -like behavior will appear.

“These individual atoms are similar to the smallest cracks that can be built,” said Wolfgang Ketter, author of the study, to the study News of the Massachusetts Institute of Technology. By bombing the atomic “cracks” repeatedly with photons, Ketterle, the 2001 Nobel Prize winner, and his team, managed to record the bewitting pattern of photons that spread on atomic cracks.

What they found, which is not surprising, is that Bohr was true. The higher their enlargement on the individual photon path, the more weaker vinical pattern, which confirms that we cannot monitor the light as a wave and a particle simultaneously. They also tried to stop the lasers carrying atoms in place – “Spring” to prepare them. Until then, it was impossible to track the path of the photon without disrupting the pattern of wave -like overlap.

“In many descriptions, the springs play a major role. But we appear, no, that the springs do not matter here; what matters is just the ambiguity of the atoms,” explained Vitaly Vidosev, the main author of the study, also at the Massachusetts Institute of Technology. “Therefore, one must use a deeper description (such as BOHR integration), which uses quantum connections between photons and atoms.”

Einstein is sometimes accused by having quantum physics. This is not necessarily true. Einstein believes that quantum theory needs more work, especially with regard to its dependence on randomness– But he never rejected it completely. He also wrote in a A famous message For physicist Max, quantum mechanics, “it is definitely imposes”, but its instinct is that it is “not the real thing … (God) does not play dice.”

Einstein had many questions about quantum mechanics, many of which are still unanswered. Since Einstein-Bohr-the discovery of the new Massachusetts Institute of Technology-the strict and provocative challenges of what physicists take is disgraced from it continues to enhance our understanding of the strange and compatible world of quantum mechanics.
