Echo Spectroscopy of Atomic Dynamics in a Gaussian Trap via Phase Imprints
Daniel Oblak, Juergen Appel, Patrick Windpassinger +3
We report on the collapse and revival of Ramsey fringe visibility when a spatially dependent phase is imprinted in the coherences of a trapped ensemble of two-level atoms. The phas…
Spin squeezing of atomic ensembles via nuclear-electronic spin entanglement
T. Fernholz, H. Krauter, K. Jensen +3
Entangled many body systems have recently attracted significant attention in various contexts. Among them, spin squeezed atoms and ions have raised interest in the field of precisi…
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…
Geometric quantum gate for trapped ions based on optical dipole forces induced by Gaussian laser beams
Peter Staanum, Michael Drewsen, Klaus Moelmer
We present an implementation of quantum logic gates via internal state dependent displacements of ions in a linear Paul trap caused by optical dipole forces. Based on a general qua…
