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…

Left-symmetric algebras, or pre-Lie algebras in geometry and physics

Dietrich Burde

In this survey article we discuss the origin, theory and applications of left-symmetric algebras (LSAs in short) in geometry in physics. Recently Connes, Kreimer and Kontsevich hav…

On deformation theory of quantum vertex algebras

Harald Grosse, Karl-Georg Schlesinger

We study an algebraic deformation problem which captures the data of the general deformation problem for a quantum vertex algebra. We derive a system of coupled equations which is…

On Convergence to Equilibrium Distribution, II. The Wave Equation in Odd Dimensions, with Mixing

T. V. Dudnikova, A. I. Komech, N. E. Ratanov +1

The paper considers the wave equation, with constant or variable coefficients in , with odd . We study the asymptotics of the distribution of the random soluti…

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…
