Researchers have built a quantum network testbed that connects several buildings on the Brookhaven Lab campus using unique portable quantum entanglement sources and an existing DOE ESnet communications fiber network\u2014a significant step in building a large-scale quantum network that can transmit information over long distances.<\/p>\n<p>\u201cIn <a href=\"https:\/\/phys.org\/tags\/quantum+mechanics\/\" rel=\"tag\" class=\"\">quantum mechanics<\/a>, the physical properties of entangled particles remain associated, even when separated by vast distances. Thus, when measurements are performed on one side, it also affects the other,\u201d said Kerstin Kleese van Dam, director of Brookhaven Lab\u2019s Computational Science Initiative (CSI). \u201cTo date, this work has been successfully demonstrated with entangled photons separated by approximately 11 miles. This is one of the largest quantum entanglement distribution networks in the world, and the longest-distance entanglement experiment in the United States.\u201d<\/p>\n<p>This quantum networking testbed project includes staff from CSI and Brookhaven\u2019s Instrumentation Division and Physics Department, as well as faculty and students from Stony Brook University. The project also is part of the Northeast Quantum Systems Center. One distinct aspect of the team\u2019s work that sets it apart from other quantum networks being run in China and Europe\u2014both long-committed to quantum information science pursuits\u2014is that the entanglement sources are portable and can be easily mounted in standard data center computer server racks that are connected to regular fiber distribution panels.<\/p>\n<p><a href=\"https:\/\/phys.org\/news\/2019-04-team-quantum-network-successful-long-distance.html\" target=\"_blank\" rel=\"noopener noreferrer\"><\/p>\n<div style=\"clear:both;\">Read more<\/div>\n<p><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scientists from the U.S. Department of Energy\u2019s Brookhaven National Laboratory, Stony Brook University, and DOE\u2019s Energy Sciences Network (ESnet) are collaborating on an experiment that puts U.S. quantum networking research on the international map.
