A machine that operates using the quantum-mechanical laws that govern the behavior of tiny objects such as molecules and atoms, was named by Science magazine scientific advance of 2010. The device, developed by physicists at the University of California at Santa Barbara, is a tiny semiconductor palette visible to the naked eye, and the researchers were able to produce purely quantum her movements. According
Science "in recognition of conceptual paths open their experiment, the ingenuity behind it and its many potential applications have been named this discovery the most important scientific breakthrough 2010 ".
" It's a simple device, a piece of aluminum nitrate about 30 micrometers long, almost the width of a human hair and dance. It moves at a rate of 6,000 million moves per second to the BBC said Robert Coontz, deputy news editor for physical sciences at Science.
What physicists Andrew Cleland and John Martins did was cool your device with liquid helium to it reached a "ground state", ie the lowest energy state that any object can possess.
The "dance" of this section is not a traditional dance. We know that all man-made objects move in accordance the laws of classical mechanics but how this palette is moved can only be explained under the laws of quantum mechanics.
"This is a traditional object," says Robert Coontz, but by getting placed in that state of very low energy behaves differently. " Quantum World
"Physicists for some 100 years have known that there are two different worlds: the ordinary world of everyday experiences that follow a series of physical laws and the physical world of tiny things: molecules, atoms and subatomic particles obey quantum rules that call. "
These rules are different from classical physical laws and scientists have failed to understand why things should be subject to another tiny other physical laws.
And so far never been able to observe the strange effects of quantum physics.
The importance of winning research is that the device is visible to the naked eye and it was created entirely by men, which demonstrates for the first time the differences between physical objects.
"This research shows that we can explore the line between" real "world and the world of tiny objects," says Robert Coontz.
"And this will help us understand why this gap exists, if it exists, and where it is located, which is something that physicists have wondered over the past 100 years," adds the expert.
And in practice, the study raises a variety of possibilities ranging from the potential quantum of light control, electric currents and movement to possibly someday be able to erase the boundary between the quantum world and the real world. (BBC)
