A limitation of these techniques has been the ability to emit photons at high rates. \u201cOne of the most important figures of merit for single-photon sources is brightness \u2014 or collected photons per second \u2014 because the brighter it is, the more data you can transmit securely with quantum encryption,\u201d said Yousif Kelaita of <a href=\"https:\/\/www.stanford.edu\/\">Stanford University<\/a>.<\/p>\n<p>In the journal <a href=\"https:\/\/www.osapublishing.org\/ome\/home.cfm\"><em>Optical Materials Express<\/em><\/a><em>,<\/em> from <a href=\"http:\/\/www.osa.org\/en-us\/home\/\">The Optical Society<\/a> (OSA), Kelaita and his colleagues show that their new nanocavity significantly increased the emission brightness of quantum dots \u2014 nanometer-scale semiconductor particles that can emit single photons.<\/p>\n<p><!-- Link: <a href=\"http:\/\/www.scienceandtechnologyresearchnews.com\/ultra-small-nanocavity-advances-technology-for-quantum-based-data-encryption\/\">http:\/\/www.scienceandtechnologyresearchnews.com\/ultra-small-...ncryption\/<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>What\u2019s next?
