Creating squeezed and non-classical collective motional many-body states through stroboscopic Rydberg dressing
Roman WuÃler, Chris Nill, Sylvain de Léséleuc +2
Realizing conditional quantum operations, e.g., quantum gates, for quantum computing and simulation requires controlled interactions between particles. Often, these interactions de…
Spectroscopic signatures of emergent elementary excitations in a kinetically constrained long-range interacting two-dimensional spin system
Tobias Kaltenmark, Chris Nill, Christian Groà +1
Lattice spin models featuring kinetic constraints constitute a paradigmatic setting for the investigation of glassiness and localization phenomena. The intricate dynamical behavior…
Entanglement of mechanical oscillators mediated by a Rydberg tweezer chain
Cedric Wind, Chris Nill, Julia Gamper +5
Mechanical systems provide a unique test bed for studying quantum phenomena at macroscopic length scales. However, realizing quantum states that feature quantum correlations among…
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…
Resonant stroboscopic Rydberg dressing: electron-motion coupling and multi-body interactions
Chris Nill, Sylvain de Léséleuc, Christian Groà +1
Rydberg dressing traditionally refers to a technique where interactions between cold atoms are imprinted through the far off-resonant continuous-wave excitation of high-lying Rydbe…
