Digital atom interferometer with single particle control on a discretized spacetime geometry
Andreas Steffen, Andrea Alberti, Wolfgang Alt +5
Engineering quantum particle systems, such as quantum simulators and quantum cellular automata, relies on full coherent control of quantum paths at the single particle level. Here…
In-situ measurement of vacuum window birefringence by atomic spectroscopy
Andreas Steffen, Wolfgang Alt, Maximilian Genske +3
We present an in-situ method to measure the birefringence of a single vacuum window by means of microwave spectroscopy on an ensemble of cold atoms. Stress-induced birefringence ca…
Electric quantum walks with individual atoms
Maximilian Genske, Wolfgang Alt, Andreas Steffen +4
We report on the experimental realization of electric quantum walks, which mimic the effect of an electric field on a charged particle in a lattice. Starting from a textbook implem…
Imprinting Patterns of Neutral Atoms in an Optical Lattice using Magnetic Resonance Techniques
Michał Karski, Leonid Förster, Jai-Min Choi +5
We prepare arbitrary patterns of neutral atoms in a one-dimensional (1D) optical lattice with single-site precision using microwave radiation in a magnetic field gradient. We give…
Microwave Control of Atomic Motion in Optical Lattices
Leonid Förster, Michał Karski, Jai-Min Choi +8
We control the quantum mechanical motion of neutral atoms in an optical lattice by driving microwave transitions between spin states whose trapping potentials are spatially offset.…
Quantum Walk in Position Space with Single Optically Trapped Atoms
Michał Karski, Leonid Förster, Jai-Min Choi +4
The quantum walk is the quantum analogue of the well-known random walk, which forms the basis for models and applications in many realms of science. Its properties are markedly dif…
