Entanglement-assisted Orientation in Space
Caslav Brukner, Nikola Paunkovic, Terry Rudolph +1
We demonstrate that quantum entanglement can help separated individuals in making decisions if their goal is to find each other in the absence of any communication between them. We…
Experimental Analysis of a 4-Qubit Cluster State
Nikolai Kiesel, Christian Schmid, Ulrich Weber +4
Linear optics quantum logic operations enabled the observation of a four-photon cluster state. We prove genuine four-partite entanglement and study its persistency, demonstrating r…
Spin gases as microscopic models for non-Markovian decoherence
L. Hartmann, J. Calsamiglia, W. Dür +1
We analyze a microscopic decoherence model in which the total system is described as a spin gas. A spin gas consists of N classically moving particles with additional, interacting…
Entanglement between Collective Operators in a Linear Harmonic Chain
Johannes Kofler, Vlatko Vedral, Myungshik S. Kim +1
We investigate entanglement between collective operators of two blocks of oscillators in an infinite linear harmonic chain. These operators are defined as averages over local opera…
Atom-molecule dark states in a Bose-Einstein condensate
K. Winkler, G. Thalhammer, M. Theis +3
We have created a dark quantum superposition state of a Rb Bose-Einstein condensate (BEC) and a degenerate gas of Rb ground state molecules in a specific ro-vibrational state u…
Addendum to "Sufficient conditions for three-particle entanglement and their tests in recent experiments"
Geza Toth, Otfried Guehne, Michael Seevinck +1
A recent paper [M. Seevinck and J. Uffink, Phys. Rev. A 65, 012107 (2002)] presented a bound for the three-qubit Mermin inequality such that the violation of this bound indicates g…
