Quantum entanglement is a startling phenomenon in which pairs or groups of particles interact with each other in a way that contradicts the classical laws of physics. One object can seemingly affect another simultaneously, even if there is no direct physical connection and is separated by long distances, such as the length of the universe.
Entanglement that Albert Einstein once described as a "scary action on distance" "It is a cornerstone of quantum mechanics – the bizarre 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 minimal environmental disturbances can disrupt the bonds between them The particles in question so far have been detected only on a tiny scale using light particles or other similarly sized atomic objects.
In a New Journal Nature study, a 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 Finland, have generated quantum entanglement to a great extent, in a world first, that our understanding promises to expand quantum physics.

"In our system we have two very small vibrating eardrums," said Aashish Clerk, a professor at the Institute for Molecular Engineering at the University of Chicago, opposite Newsweek. "When you look at just one of the eardrums, it seems to be a random movement, but when you look at both, you can see that the movement of the two eardrums is extremely correlated: when one eardrum moves up, the other moves down, etc. "
" This correlation is too strong to understand physics with the help of classical, "he said. "This entanglement is something that Einstein always found problematic, hence his term" scary remote effect.
The researchers had to eliminate all forms of environmental disturbances, they conducted the experiment at temperatures near absolute zero minus minus 459.67 degrees Surprisingly, the researchers found that their approach led to entanglements that lasted for long periods of time, sometimes up to half (19659002). The new results show that it is possible to generate exotic quantum states in relatively large objects Could have a number of significant implications.
"Entanglement is the key resource behind many possible technologies that use the least intuitive aspects of quantum mechanics, including quantum computers and new types of extremely precise sensors," says Clerk.
"This research shows that we are now able to create and stabilize the motion of large objects in these unusual entangled states, with small vibrating objects already playing a crucial role in a variety of applications – for example, as sensors and sensors Filters in Your Mobile Phone Quantum versions of these mechanical devices could have a variety of applications – for example, a kind of "bus" that could move quantum information from one type of physical system to another, "he said.
"Basically, there are fundamental questions about whether 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 it. Such experiments really prepare large objects. Quantum states are a promising way to answer these questions. "
