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…
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…
Increasing identical particle entanglement by fuzzy measurements
D. Cavalcanti, M. F. Santos, M. O. Terra Cunha +2
We investigate the effects of fuzzy measurements on spin entanglement for identical particles, both fermions and bosons. We first consider an ideal measurement apparatus and define…
Macroscopic thermal entanglement due to radiation pressure
A. Ferreira, A. Guerreiro, V. Vedral
Can entanglement and the quantum behavior in physical systems survive at arbitrary high temperatures? In this Letter we show that this is the case for a electromagnetic field mode…
Influence of molecular temperature on the coherence of fullerenes in a near-field interferometer
Klaus Hornberger, Lucia Hackermueller, Markus Arndt
We study C70 fullerene matter waves in a Talbot-Lau interferometer as a function of their temperature. While the ideal fringe visibility is observed at moderate molecular temperatu…
