Renormalization algorithm with graph enhancement
R. Hübener, C. Kruszynska, L. Hartmann +4
We introduce a class of variational states to describe quantum many-body systems. This class generalizes matrix product states which underly the density-matrix renormalization grou…
Entanglement purification protocols for all graph states
Caroline Kruszynska, Akimasa Miyake, Hans J. Briegel +1
We present multiparty entanglement purification protocols that are capable of purifying arbitrary graph states directly. We develop recurrence and breeding protocols and compare ou…
Quantum communication cost of preparing multipartite entanglement
Caroline Kruszynska, Simon Anders, Wolfgang Dür +1
We study the preparation and distribution of high-fidelity multi-party entangled states via noisy channels and operations. In the particular case of GHZ and cluster states, we stud…
