Optimal verification of entanglement in a photonic cluster state experiment
H. Wunderlich, G. Vallone, P. Mataloni +1
We report on the quantification of entanglement by means of entanglement measures on a four- and a six- qubit cluster state realized by using photons entangled both in polarization…
Measuring entanglement in condensed matter systems
M. Cramer, M. B. Plenio, H. Wunderlich
We show how entanglement may be quantified in spin and cold atom many-body systems using standard experimental techniques only. The scheme requires no assumptions on the state in t…
Highly-efficient estimation of entanglement measures for large experimentally created graph states via simple measurements
H. Wunderlich, S. Virmani, M. B. Plenio
Quantifying experimentally created entanglement could in principle be accomplished by measuring the entire density matrix and calculating an entanglement measure of choice thereaft…
Estimating Purity and Entropy in Stabilizer State Experiments
Harald Wunderlich, Martin B. Plenio
Many experiments in quantum information aim at creating graph states. Quantifying the purity of an experimentally achieved graph state could in principle be accomplished using full…
A glance beyond the quantum model
Miguel Navascues, Harald Wunderlich
One of the most important problems in Physics is how to reconcile Quantum Mechanics with General Relativity. Some authors have suggested that this may be realized at the expense of…
Quantitative verification of entanglement and fidelities from incomplete measurement data
Harald Wunderlich, Martin B. Plenio
Many experiments in quantum information aim at creating multi-partite entangled states. Quantifying the amount of entanglement that was actually generated can, in principle, be acc…
Two-dimensional cluster-state preparation with linear ion traps
Harald Wunderlich, Christof Wunderlich, Kilian Singer +1
We present schemes to prepare two-dimensional cluster states [H. J. Briegel and R. Raussendorf, Phys. Rev. Lett. {\bf 86}, 910 (2001)] with atomic ions confined in a micro-structur…
