Sideband cooling and coherent dynamics in a microchip multi-segmented ion trap
Stephan Schulz, Ulrich Poschinger, Frank Ziesel +1
Miniaturized ion trap arrays with many trap segments present a promising architecture for scalable quantum information processing. The miniaturization of segmented linear Paul trap…
Transport of ions in a segmented linear Paul trap in printed-circuit-board technology
G. Huber, T. Deuschle, W. Schnitzler +3
We describe the construction and operation of a segmented linear Paul trap, fabricated in printed-circuit-board technology with an electrode segment width of 500 microns. We prove…
A number filter for matter-waves
G. Nandi, A. Sizmann, J. Fortágh +1
In current Bose-Einstein condensate experiments, the shot-to-shot variation of atom number fluctuates up to 10%. In here, we present a procedure to suppress such fluctuations by us…
A reversible theory of entanglement and its relation to the second law
Fernando G. S. L. Brandao, Martin. B. Plenio
We consider the manipulation of multipartite entangled states in the limit of many copies under quantum operations that asymptotically cannot generate entanglement. As announced in…
Photon storage in Lambda-type optically dense atomic media. IV. Optimal control using gradient ascent
Alexey V. Gorshkov, Tommaso Calarco, Mikhail D. Lukin +1
We use the numerical gradient ascent method from optimal control theory to extend efficient photon storage in Lambda-type media to previously inaccessible regimes and to provide si…
Gauss sum factorization with cold atoms
M. Gilowski, T. Wendrich, T. Müller +4
We report the first implementation of a Gauss sum factorization algorithm by an internal state Ramsey interferometer using cold atoms. A sequence of appropriately designed light pu…
