It is known that topological operations (braiding and fusion of anyons) are not computationally universal in this model. I demonstrate that universal set of gates can be reliably simulated with additional very noisy non-topological operations (such s direct short-range interaction between anyons) if the noise level is below threshold value about 15%. http://online.kitp.ucsb.edu/online/qubit_c06/bravyi/ Wed, 17 May 2006 10:40:00 -0700 52:04 Quantum Computation in Semiconductor Nanostructures http://online.kitp.ucsb.edu/online/qubit_c06/dassarma/ Sankar Das Sarma (Maryland) (Sankar Das Sarma (Maryland)) Sankar Das Sarma (Maryland) http://online.kitp.ucsb.edu/online/qubit_c06/dassarma/ Fri, 19 May 2006 10:40:00 -0700 54:01 Disentanglement by a Point Contact http://online.kitp.ucsb.edu/online/qubit_c06/fendley/ Paul Fendley (Univ.

As an outlook we will discuss several aspects of potential proof-of-principle realizations of topologically protected memory and computation in such systems. http://online.kitp.ucsb.edu/online/qubit_c06/lukin/ Tue, 16 May 2006 14:55:00 -0700 52:12 Spin-based Qubits: Recent Experiments and Integration Scenarios http://online.kitp.ucsb.edu/online/qubit_c06/marcus/ Charlie Marcus (Harvard) (Charlie Marcus (Harvard)) Charlie Marcus (Harvard) http://online.kitp.ucsb.edu/online/qubit_c06/marcus/ Fri, 19 May 2006 11:35:00 -0700 56:13 Decoherence from Two-Level States http://online.kitp.ucsb.edu/online/qubit_c06/martinis/ John Martinis (UCSB) (John Martinis (UCSB)) John Martinis (UCSB) http://online.kitp.ucsb.edu/online/qubit_c06/martinis/ Thu, 18 May 2006 16:20:00 -0700 59:02 An Optical Lattice Toolbox: Optical potentials for coherent control of atoms. http://online.kitp.ucsb.edu/online/qubit_c06/porto/ Trey Porto (NIST) (Trey Porto (NIST)) Trey Porto (NIST) http://online.kitp.ucsb.edu/online/qubit_c06/porto/ Tue, 16 May 2006 16:20:00 -0700 52:21 Non-Abelian Quantum Hall States: Properties and Prospects http://online.kitp.ucsb.edu/online/qubit_c06/read/ Nick Read (Yale Univ.)
