Topological cluster state quantum computing
Austin G. Fowler, Kovid Goyal
The quantum computing scheme described in Phys. Rev. Lett. 98, 190504 (2007), when viewed as a cluster state computation, features a 3-D cluster state, novel adjustable strength er…
Topological fault-tolerance in cluster state quantum computation
Robert Raussendorf, Jim Harrington, Kovid Goyal
We describe a fault-tolerant version of the one-way quantum computer using a cluster state in three spatial dimensions. Topologically protected quantum gates are realized by choosi…
Purification of large bicolorable graph states
Kovid Goyal, Alex McCauley, Robert Raussendorf
We describe novel purification protocols for bicolorable graph states. The protocols scale efficiently for large graph states. We introduce a method of analysis that allows us to d…
A fault-tolerant one-way quantum computer
R. Raussendorf, J. Harrington, K. Goyal
We describe a fault-tolerant one-way quantum computer on cluster states in three dimensions. The presented scheme uses methods of topological error correction resulting from a link…
Noise induced loss of entanglement
Kovid Goyal
The disentangling effect of repeated applications of the bit flip channel (I\otimesσ_x) on bipartite qubit systems is analyzed. It is found that the rate of loss of entanglement is…
