Stochastic One-Way Quantum Computing with Ultracold Atoms in Optical Lattices
Michael C. Garrett, David L. Feder · arXiv (Cornell University) · 2006
The cluster state, the highly entangled multipartite initial state required for one-way quantum computing, can be generated from a gas of ultracold atoms confined in a 2D optical lattice. In practice, a systematic phase error is expected, resulting in imperfect cluster states. We present a solution to this problem, wherein the teleportation protocol is necessarily stochastic if the value of the phase error is not known.
