Magic running- and standing-wave optical traps for Rydberg atoms
Lukas Ahlheit, Chris Nill, Daniil Svirskiy +6
Magic trapping of ground and Rydberg states, which equalizes the AC Stark shifts of these two levels, enables increased ground-to-Rydberg state coherence times. We measure via phot…
Nonreciprocal recovery of electromagnetically induced transparency by wavenumber mismatch in hot atoms
Lida Zhang, Nina Stiesdal, Hannes Busche +3
For multi-level systems in hot atomic vapors the interplay between the Doppler shift due to atom velocity and the wavenubmer mismatch between driving laser fields strongly influenc…
Quantum Optics with Rydberg Superatoms
Jan Kumlin, Christoph Braun, Christoph Tresp +3
Quantum optics based on highly excited atoms, also known as Rydberg atoms, has cemented itself as a powerful platform for the manipulation of light at the few-photon level. The Ryd…
Creation of non-classical states of light in a chiral waveguide
Kevin Kleinbeck, Hannes Busche, Nina Stiesdal +3
Creating non-classical states of light from simple quantum systems together with classical resources is a challenging problem. We show how chiral emitters under a coherent drive ca…
Controlled multi-photon subtraction with cascaded Rydberg superatoms as single-photon absorbers
Nina Stiesdal, Hannes Busche, Kevin Kleinbeck +4
The preparation of light pulses with well-defined quantum properties requires precise control at the individual photon level. Here, we demonstrate exact and controlled multi-photon…
Non-exponential decay of a collective excitation in an atomic ensemble coupled to a one-dimensional waveguide
Jan Kumlin, Kevin Kleinbeck, Nina Stiesdal +3
We study the dynamics of a single excitation coherently shared amongst an ensemble of atoms and coupled to a one-dimensional wave guide. The coupling between the matter and the lig…
Observation of collective decay dynamics of a single Rydberg superatom
Nina Stiesdal, Hannes Busche, Jan Kumlin +3
We experimentally investigate the collective decay of a single Rydberg superatom, formed by an ensemble of thousands of individual atoms supporting only a single excitation due to…
Observation of three-body correlations for photons coupled to a Rydberg superatom
Nina Stiesdal, Jan Kumlin, Kevin Kleinbeck +6
We report on the experimental observation of non-trivial three-photon correlations imprinted onto initially uncorrelated photons through interaction with a single Rydberg superatom…
