Sorry Einstein, scientists have found evidence of quantum entanglement

One of the strangest phenomena that science has ever encountered is quantum entanglement - a phenomenon in which two particulate matter is tightly coupled no matter how far away they are, even up to many years. the light. The state of a particle will immediately affect the state of the other particle through that tight bond.

Before this phenomenon, genius Einstein had come to the final decision that this incident was so bizarre that it was difficult to exist, he called this quantum entanglement "a bizarre effect".

But the newly completed tests are the clearest evidence for this quantum entanglement to actually happen, and at the same time prove what we still know is that this universe is still as strange as It has been the same since ancient times.

This universe is still as strange as it used to be.

Quantum puppet itself is only a theory and very difficult to prove , although physicists can follow it easily (quantum tangles are the most basic of quantum computers). but we cannot know whether there is an invisible thing that affects the state of the two particles, making the result we see "seem" to be the result we want to see.

Why do two particles have such a connection, which can be identical at very long distances (from a few meters to a few light years), scientists only need to know the exact measurements of a seeds to figure out the state of the other particle?

There have been many trials during the last century trying to prove this quantum entanglement, but no one can explain it completely. Even Einstein's "tangled hair genius" , to the final decision, only considered it "a bizarre effect" without any explanation to the root.

Einstein did not deny that it was a quantum entanglement phenomenon , but he suggested that there are some hidden variables that have caused this phenomenon.

In the 1960s, physicist John Bell created a special "test" to measure confusion about whether they were really tangled or that a variable had changed the test results. John Bell's experiment was two separate measurements with two tangled particles, to see which results were more convincing.

John Bell's experiment was two separate measurements with two tangled particles, to see which results were more convincing.

"Bell has demonstrated that, according to statistical parameters, the correlation between the results exceeds the threshold and cannot be explained by the fact that these particles have hidden properties , " Elizabeth Gibney from the magazine Prestigious Nature said.

"Instead, the results show that the measurement of a particle has mysteriously corrected the properties of that particle."

Scientists soon realized that there were restrictions imposed on physicist Bell with his experiments, which had holes opening up other explanations.

One of the loopholes is probably that particles share information with each other at the speed of light, and our measuring tools are too slow to catch up. Or perhaps the end result was affected when some of the seeds were not fully measured.

The other two holes were finally resolved in 2015, when a historic test caused quantum entanglement to overcome the most difficult test, by eliminating both.

However, there is one more hole, the vulnerability is named freedom of choice.

Gibney explains that, every time we re-apply Bell's test, we assume that scientists who test can choose the measurement they perform on each particle of the photon pair. shining:

"But some mysterious effects may affect both the particle and the type of test being applied (or they affect the more reasonable or reasonable options, they limit the choices that may be use, to create an image of confusion ".

Understandably, imagine this universe is a restaurant with a 10-course menu.

"You think you can call anything on that list, but then they tell you," We are out of chicken, "so it turns out you can only order 5 items." one person from the research team, Andrew Friedman from MIT said.

"You still have the freedom to choose with the remaining 5 items, but you misunderstood your choice right from the first second."

With quantum puppet tests, too, "there may be unknown binding conditions, rules that limit your choice , " Friedman concludes. These unknown factors can deceive us, that quantum entanglement is real.

One of those who often causes trouble is gravity , perhaps their influence has limited the measures we can take, because we perform those tests on Earth, where gravity is exist and "rage" from the old days of the Earth.

One of the gaps is probably that particles share information with each other at the speed of light.

So how do we eliminate the gap of freedom of choice when this Universe itself limits the ability to measure?

"We limit the choices that this universe makes , " Friedman said.

In the past, researchers have tried to overcome this vulnerability by using a random number generation system, which at the last minute randomly chooses which properties to measure before the particulate matter arrives. Get the end point.

That means the county has very little time to share information with each other, and the end result will show that the grain is just "in a tangle" , as Einstein had anticipated.

This test is feasible, but it only eliminates the effect of hidden variables for several microseconds before the matter particle is released. But what if the variable affected the particle before that moment?

A team of researchers from MIT, Vienna University, Austria and many other research institutes from China and Germany decided to use light to push back the length of time, making the effects invisible completely removed from the test.

The test this time determines the location of red and blue in certain properties that will be measured in the way of the particle. Two telescopes will be placed to see if the light being illuminated is green or red, any color detected will determine the properties measured in the tangled particles.

Because the color of light will not be altered on their flight path, any influence factor will not work on the particle and cannot determine the particle properties before being measured.

The test this time determines the location of red and blue in certain properties that will be measured in the way of the particle.

The light used is light from a star a long time ago, and if the other particle properties were previously defined, it must be determined 600 years ago.

The test does not close the entire gap of freedom of choice , but for the first time, it is possible to identify the "remote bizarre effect" that exists, at least 600 years ago. . The next goal of scientists is to push this 600-year limit away.

Friedman thinks they can do that by using light from farther places, even pushing back billions of years. But where is the end point, the first point of the universe is the Big Bang?

It is possible that this universe limits the choice of the particle from the first point, because every measurement is predetermined from the moment Bing Bang happens. Bell's test will not be able to push far from the time when light has not yet appeared, so the gap of freedom of choice will never be completely closed.

Even so, Friedman concluded that endless possibilities were too interesting and they could not help but discover."For us, this is a beneficial situation. Or we will increasingly close this gap, and we will be more confident in the quantum assumptions that are put, or they are We will find evidence of a completely new kind of physics. "
