Entanglement purification for Quantum Computation
W. Dür, H. -J. Briegel
We show that thresholds for fault-tolerant quantum computation are solely determined by the quality of single-system operations if one allows for d-dimensional systems with $8 \leq…
Quantum Communication and Decoherence
Hans Aschauer, Hans J. Briegel
In this contribution we will give a brief overview on the methods used to overcome decoherence in quantum communication protocols. We give an introduction to quantum error correcti…
Computational Model for the One-Way Quantum Computer: Concepts and Summary
R. Raussendorf, H. J. Briegel
The one-way quantum computer (QCc) is a universal scheme of quantum computation consisting only of one-qubit measurements on a particular entangled multi-qubit state, the cluster s…
Quantum random walks in optical lattices
W. Dür, R. Raussendorf, V. M. Kendon +1
We propose an experimental realization of discrete quantum random walks using neutral atoms trapped in optical lattices. The random walk is taking place in position space and exper…
