This allows scientists to make more robust measurements.<\/p>\n<p>What makes the Oxford team\u2019s experiment exciting is that they <i>entangled<\/i><span> two separate atomic clocks at a distance of about two meters. <\/span><\/p>\n<p><span>Per the team\u2019s <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/s41586-022-05088-z\">research paper<\/a>:<\/span><\/p>\n<blockquote><p><span>Measurements on independent systems are limited by the standard quantum limit; measurements on entangled systems can surpass the standard quantum limit to reach the ultimate precision allowed by quantum theory\u2014the Heisenberg limit.<\/span><\/p>\n<\/blockquote>\n<p><strong>Background:<\/strong> Scientists have successfully entangled atomic clocks at the microscopic level, but to the best of our knowledge this is the largest distance at which two optical atomic clocks have ever been entangled.<\/p>\n<p>Essentially, the Oxford team\u2019s managed to create a two-node network of atomic clocks at a very useful distance \u2014 one that, theoretically, could be increased.<\/p>\n<p>What\u2019s more, hypothetically speaking, there\u2019s no limit on the number or type of nodes that could be added to a network of entangled atomic clocks.<\/p>\n<p>Scientists currently use a math-based consensus between dozens or hundreds of different atomic clocks to come up with the most accurate possible measurements. But entangled clocks are, theoretically, capable of much greater accuracy.<\/p>\n<p><strong>Quick take:<\/strong> The potential implications for this research are humongous. The more accurately we can measure the passage of time, the closer we come to unraveling some of the universe\u2019s greatest mysteries.<\/p>\n<p>If we\u2019re able to develop a massive network of atomic clocks that spread out into space, it\u2019s possible we could start forming a sort of reverse image of the universe that reveals dark matter in real time.<\/p>\n<p>US and Canadian researchers predicted the usefulness of such a network in <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/nphys3137\">a 2014 paper<\/a> detailing a dark matter detector based on synchronized atomic clocks:<\/p>\n<blockquote><p>During the encounter with an extended dark-matter object, as it sweeps through the network, initially synchronized clocks will become desynchronized. Time discrepancies between spatially separated clocks are expected to exhibit a distinct signature, encoding the defect\u2019s space structure and its interaction strength with atoms.<\/p>\n<\/blockquote>\n<p>In other words: if dark matter\u2019s out there, the Oxford team\u2019s recent breakthrough might be our best lead yet. And, best of all, there\u2019s not much downside to pursuing this research. Even if the dark matter theory doesn\u2019t pan out, there are innumerable practical uses for more accurate atomic clocks.<\/p>\n<p><em>H\/t: Mike Mcrae, <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.sciencealert.com\/physicists-just-entangled-a-pair-of-atomic-clocks-six-feet-apart\">Science Alert<\/a><\/em>\n                        <\/div>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
