Weird quantum phenomenon demonstrated on a massive scale in the world first



Quantum entanglement is an amazing phenomenon in which pairs, or groups, of particles interact with each other in such a way that they defy the classical laws of physics. One object can apparently influence another simultaneously, even if they have no direct physical connection and are separated by great distances, such as the length of the universe.

Entanglement, which was once described by Albert Einstein as "spooky action at a distance", "is a cornerstone of quantum mechanics – the strange physics of the very small – and plays an important role in potentially revolutionary technologies such as quantum computers

It is extremely difficult to produce artificially because even the smallest environmental disturbances can break the connections between the particles in question, so until now, it has only been demonstrated on a small scale using particles of light or other atomic objects of size similar.

However, in a new journal Nature study, an international team of scientists from the University of New South Wales, Australia, the University of Chicago and the universities of Jyväskylä and Aalto, both in Finla nd, have generated quantum entanglements on a massive scale, in a world first that promises to expand our Understanding of quantum physics.

The team managed to entangle the movement of two aluminum patches on a silicon chip by applying microwaves to the circuit, which caused them to vibrate at high frequencies. These patches are small, measuring only 15 micrometers wide, about the width of a human hair, but they contain many billions of atoms, which is massive for the quantum scale, and much larger than any object that has been entangled before.

"In our system, we have two very small vibration patches," said Aashish Clerk, a professor at the Institute of Molecular Engineering at the University of Chicago, at Newsweek. "If you only look at one of the patches, its movement seems to be completely random, but if we look at both, we would see that the movement of the two patches is extremely correlated: when one patch moves up, the other moves down, etc. "

" This correlation is too strong to be understood using physics, "he said. "This entanglement is something that Einstein always considered problematic, hence his term" spooky action at a distance ".

The researchers had to eliminate all forms of environmental disturbances, so they conducted the experiment at temperatures close to zero absolute minus 459.67 degrees Fahrenheit. Surprisingly, the researchers found that their approach led to entanglement states that lasted long periods of time, sometimes up to half an hour.

The new findings show that it is possible to generate exotic quantum states in relatively large objects, which could have a number of significant implications.

"Entanglement is the key resource behind many potential technologies that take advantage of the most counter-intuitive aspects of quantum mechanics, including quantum computers and new types of extremely sensitive sensors precise, "said Clerk.

"This research demonstrates that we now have the ability to generate and stabilize the movement of large objects in these unusual tangled states. Small objects that vibrate already play a crucial role in several different applications, for example, as sensors and filters in Your cell phone Quantum versions of these mechanical devices could have a lot of applications, for example, as a kind of "bus" that could transfer quantum information from one type of physical system to another, "he said.

"More fundamentally, there are basic questions about whether it is necessary to modify the laws of quantum mechanics when describing large macroscopic objects," he added. "Some believe that the poorly understood interaction of quantum mechanics and gravity requires this. type of experiments that prepare large objects in truth Quantum states are a promising route to help answer these questions.
