Iterative entanglement distillation for finite resources
Stefan Probst-Schendzielorz, Thorsten Bschorr, Matthias Freyberger
We discuss a specific entanglement distillation scheme under the constraint of finite samples of entangled qubit pairs. It is shown that an iterative process can be explicitly form…
Quantum tunneling of semifluxons
E. Goldobin, K. Vogel, O. Crasser +4
We consider a system of two semifluxons of opposite polarity in a 0-pi-0 long Josephson junction, which classically can be in one of two degenerate states: up-down or down-up. When…
Hecke actions on certain strongly modular genera of lattices
Gabriele Nebe, Maria Teider
We calculate the action of some Hecke operators on spaces of modular forms spanned by the Siegel theta-series of certain genera of strongly modular lattices closely related to the…
Extracting Atoms on Demand with Lasers
Bernd Mohring, Marc Bienert, Florian Haug +3
We propose a scheme that allows to coherently extract cold atoms from a reservoir in a deterministic way. The transfer is achieved by means of radiation pulses coupling two atomic…
The local lifting problem for dihedral groups
Irene I. Bouw, Stefan Wewers
Let be the dihedral group of order , where is an odd prime. Let an algebraically closed field of characteristic . We show that any action of on the ring…
Growth of GaMnAs under near-stoichiometric conditions
V. Avrutin, D. Humienik, S. Frank +5
We studied the effect of the V/III flux ratio and substrate temperature on magnetotransport properties and lattice parameters of Ga0.96Mn0.04As grown by molecular beam epitaxy. For…
