Quantum computing via measurements only
Robert Raussendorf, Hans J. Briegel
A quantum computer promises efficient processing of certain computational tasks that are intractable with classical computer technology. While basic principles of a quantum compute…
Private entanglement over arbitrary distances, even using noisy apparatus
Hans Aschauer, Hans J. Briegel
We give a security proof of quantum cryptography based entirely on entanglement purification. Our proof applies to all possible attacks (individual and coherent). It implies the se…
The Schmidt Measure as a Tool for Quantifying Multi-Particle Entanglement
J. Eisert, H. -J. Briegel
We present a measure of quantum entanglement which is capable of quantifying the degree of entanglement of a multi-partite quantum system. This measure, which is based on a general…
Persistent entanglement in arrays of interacting particles
Hans J. Briegel, Robert Raussendorf
We study the entanglement properties of a class of qubit quantum states that are generated in arrays of qubits with an Ising-type interaction. These states contain a large amou…
