Journal ArticleDOI
Quantum Walk in Position Space with Single Optically Trapped Atoms
Michał Karski,Leonid Förster,Jai Min Choi,Andreas Steffen,Wolfgang Alt,Dieter Meschede,Artur Widera +6 more
TL;DR: In this experiment, a quantum walk on the line with single neutral atoms is implemented by deterministically delocalizing them over the sites of a one-dimensional spin-dependent optical lattice and its spatial coherence is demonstrated.
Journal ArticleDOI
Nearest-neighbor detection of atoms in a 1D optical lattice by fluorescence imaging.
TL;DR: The diffraction limit in fluorescence imaging of neutral atoms in a sparsely filled one-dimensional optical lattice is overcome and the method points towards characterization of correlated quantum states in optical lattices systems with filling factors of up to one atom per lattice site.
Journal ArticleDOI
Super-resolution microscopy of single atoms in optical lattices
Andrea Alberti,Carsten Robens,Wolfgang Alt,Stefan Brakhane,Michał Karski,René Reimann,Artur Widera,Dieter Meschede +7 more
TL;DR: In this article, a deconvolution method was proposed to determine the lattice-site positions of single atoms in an optical lattice with high reliability, even for limited acquisition time or optical resolution.
Journal ArticleDOI
Microwave control of atomic motion in optical lattices.
Leonid Förster,Michał Karski,Jai Min Choi,Andreas Steffen,Wolfgang Alt,Dieter Meschede,Artur Widera,Enrique Montano,Jae Hoon Lee,Worawarong Rakreungdet,Poul S. Jessen +10 more
TL;DR: It is shown that microwaves can drive well resolved transitions between motional states in maximally offset, shallow lattices, and thus in principle allow for coherent control of long-range quantum transport.
Journal ArticleDOI
Digital atom interferometer with single particle control on a discretized space-time geometry
Andreas Steffen,Andrea Alberti,Wolfgang Alt,Noomen Belmechri,Sebastian Hild,Michał Karski,Artur Widera,Dieter Meschede +7 more
TL;DR: This work presents an atom interferometer operating with single trapped atoms, where single particle wave packets are controlled through spin-dependent potentials, yielding insight into decoherence mechanisms.
