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…
Tangential Touch between Free and Fixed Boundaries in a Problem from Superconductivity
Norayr Matevosyan
In this paper we study regularity properties of the free boundary problem from superconductivity close to a fixed boundary. If the origin is a free boundary point, then we show tha…
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…
Instantaneous Bethe-Salpeter Equation with Exact Propagators
Wolfgang Lucha, F. F. Schoberl
Consequent application of the instantaneous approximation to both the interaction and all propagators of the bound-state constituents allows us to forge, within the framework of th…
