Novel Ordered States of Electrons

Chetan Nayak, UCLA, DMR-0411800• With M. Freedman and S. Das Sarma, the PI proposed a device based on a possible new state of matter (non-Abelian FQH state)

• A step towards a topological quantum computer =>

Exploit robustness of topological phases to perform fault-tolerant quantum computation.

With M. Freedman and K. Walker,

a quantum computing architecture built around this device.

With P. Fendley and M.P.A. Fisher,

analyzed the properties of point contacts in non-Abelian quantum Hall states, the basic building blocks of such devices.

With several collaborators, analogous set-up in cold-atom systems proposed.
