Instead of storing qubits in properties of particles, such as an electron's spin, they suggested that qubits could be encoded into properties shared by the whole material, and so would be harder to disrupt (<I>New Scientist</I>, 24 January 2004, p 30).</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.newscientist.com/article/mg19325954.200?DCMP=NLC-nletter&nsref=mg19325954.200">Physicists told Freedman that the material he needed simply didn't exist, but Joel Helton's group at MIT might just prove them wrong. The material would be a string-net liquid with elementary and quasi-particles at the end of each string. Physicists could manipulate quasi-particles with electric fields, braiding them around each other, encoding information in the number of times the strings twist and knot, says Freedman. A disturbance might knock the whole braid, but it won't change the number of twists</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/C80A746F-19EC-4C8A-8D1E-E19C36C9678A/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
