Using the same principle, NIST physicists have now \u201ccooled a mechanical object to a temperature lower than previously thought possible,\u201d passing the so-called \u201cquantum limit\u201d which imposes limits on accuracy for quantum scale measurements.<\/p>\n<p>Described in <a href=\"http:\/\/www.nature.com\/nature\/journal\/v541\/n7636\/full\/nature20604.html\">a paper<\/a> titled \u201cSideband cooling beyond the quantum backaction limit with squeezed light,\u201d published Thursday in the journal Nature, the technique could theoretically be used to cool objects to absolute zero, when matter exhibits almost no energy or motion.<\/p>\n<p>The researchers took a microscopic mechanical aluminum drum \u2014 diameter of 20 micrometers and thickness of 100 nanometers \u2014 and put it in a superconducting circuit, which itself was placed inside an electromagnetic cavity. Microwave photons of \u201csqueezed light\u201d \u2014 the photons were purified, or stripped, of the unwanted fluctuations that could cause heating \u2014 were then used to create resonance in the cavity, which in turn caused the drum to beat. As the cavity filled up with photons, they leaked out, carrying with them phonons \u2014 mechanical units of energy \u2014 and thus lowering the total energy state of the drum to just a fifth of a single quantum of energy.<\/p>\n<p><!-- Link: <a href=\"http:\/\/www.msn.com\/en-au\/money\/technology\/new-cooling-technique-could-aid-development-of-quantum-computers\/ar-AAlMSUU\">http:\/\/www.msn.com\/en-au\/money\/technology\/new-cooling-techni...ar-AAlMSUU<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nice.
