Three qubits can be entangled in two inequivalent ways

Invertible local transformations of a multipartite system are used to define equivalence classes in the set of entangled states. This classification concerns the entanglement properties of a single… Expand

Quantum repeaters based on entanglement purification

- W. Dur, H. Briegel, J. Cirac, P. Zoller
- Physics
- 31 August 1998

We study the use of entanglement purification for quantum communication over long distances. For distances much longer than the coherence length of a corresponding noisy quantum channel, the fidelity… Expand

Entanglement in Graph States and its Applications

- M. Hein, W. Dur, J. Eisert, R. Raussendorf, M. V. D. Nest, H. Briegel
- Physics, Mathematics
- 11 February 2006

Graph states form a rich class of entangled states that exhibit important aspects of multi-partite entanglement. At the same time, they can be described by a number of parameters that grows only… Expand

Measurement-based quantum computation

- H. Briegel, D. Browne, W. Dur, R. Raussendorf, M. V. D. Nest
- Physics
- 6 October 2009

Quantum computation offers a promising new kind of information processing, where the non-classical features of quantum mechanics are harnessed and exploited. A number of models of quantum computation… Expand

Distillability and partial transposition in bipartite systems

- W. Dur, J. Cirac, M. Lewenstein, D. Bruß
- Physics
- 6 October 1999

Institut fu¨r Theoretische Physik, Universit¨at Hannover, D-30167 Hannover, Germany(February 1, 2008)We study the distillability of a certain class of bipartitedensity operators which can be obtained… Expand

Classification of multiqubit mixed states: Separability and distillability properties

We give a complete, hierarchic classification for arbitrary multiqubit mixed states based on the separability properties of certain partitions. We introduce a family of N-qubit states to which any… Expand

Fundamentals of universality in one-way quantum computation

- M. V. D. Nest, W. Dur, A. Miyake, H. Briegel
- Physics
- 12 February 2007

In this paper, we build a framework allowing for a systematic investigation of the fundamental issue: 'Which quantum states serve as universal resources for measurement-based (one-way) quantum… Expand

Separability and Distillability of Multiparticle Quantum Systems

- W. Dur, J. Cirac, R. Tarrach
- Mathematics, Physics
- 4 March 1999

We present a family of 3-qubit states to which any arbitrary state can be depolarized. We fully classify those states with respect to their separability and distillability properties. This provides a… Expand

Classical simulation versus universality in measurement-based quantum computation

- M. V. D. Nest, W. Dur, G. Vidal, H. Briegel
- Physics
- 7 August 2006

We investigate for which resource states an efficient classical simulation of measurement-based quantum computation is possible. We show that the Schmidt-rank width, a measure recently introduced to… Expand

Multiparticle entanglement purification for two-colorable graph states (20 pages)

- H. Aschauer, W. Dur, H. Briegel
- Physics
- 10 May 2004

We investigate multiparticle entanglement purification schemes which allow one to purify all two colorable graph states, a class of states which includes, e.g., cluster states,… Expand
