They load atoms into a regular array of sites, and then split each site into a double well, which is a classic test system for quantum theories. This is cool not only because it was done by people I know, but also because it&#8217;s really similar to work that I did as a post-doc.<\/li>\n<li>A French group has made a <a href=\"http:\/\/physicsweb.org\/articles\/news\/11\/5\/21\/1?rss=2.0\">single electron source<\/a>, that produces, well, single electrons more or less on demand. Like everybody else in the world, they pitch this as a potential tool for quantum computing, but it&#8217;s kind of cool in its own right.<\/li>\n<li>Things keep getting weirder with <a href=\"http:\/\/scienceblogs.com\/principles\/2007\/05\/the_mystery_of_supersolid_heli.php\">&#8220;supersolid&#8221; helium<\/a>, as <a href=\"http:\/\/physicsweb.org\/articles\/news\/11\/5\/22\/1?rss=2.0\">new neutron diffraction measurements<\/a> probing the distribution of states in the &#8220;supersolid&#8221; don&#8217;t show the distribution you would expect. something weird is going on there.<\/li>\n<li>Misha Lukin&#8217;s group at Harvard has <a href=\"http:\/\/www.eurekalert.org\/pub_releases\/2007-05\/hu-ssn053007.php\">demonstrated the manipulation of single nuclear spins in diamond<\/a>. This is yet another experiment with a quantum computing connection, as you might conceivably be able to use these sorts of spins as qubits. And, really, how cool would it be to make a quantum computer out of a block of diamond? It&#8217;d be sparkly in multiple states at the same time.<\/li>\n<li>Finally, a group at NIST has set a <a href=\"http:\/\/www.eurekalert.org\/pub_releases\/2007-06\/nios-lr060107.php\">new distance record for quantum key distribution<\/a>, sending entangled photons through 200 km of optical fiber. This isn&#8217;t as cool as the headline made me think at first&#8211; I thought this was a new open-air limit, but it&#8217;s not. It&#8217;s still neat stuff, though, hence the link.<\/li>\n<\/ul>\n<p>And there&#8217;s what I&#8217;ve been reading in physics news in the past week or so.<\/li>\n","protected":false},"excerpt":{"rendered":"<p>Once again, physics news stories are piling up in my RSS reader, so here&#8217;s a collection of recent stuff: My old group at NIST has done cool things with Bose-Eisntein condensates in an optical lattice.
