Visualizing Entanglement in multi-Qubit Systems
Jonas Bley, Eva Rexigel, Alda Arias +8
In the field of quantum information science and technology, the representation and visualization of quantum states and related processes are essential for both research and educati…
Realization of a Rydberg-dressed Ramsey interferometer and electrometer
A. Arias, G. Lochead, T. M. Wintermantel +2
We present the experimental realization and characterization of a Ramsey interferometer based on optically trapped ultracold potassium atoms, where one state is continuously couple…
A versatile, high-power 460nm laser system for Rydberg excitation of ultracold potassium
Alda Arias, Stephan Helmrich, Christoph Schweiger +3
We present a versatile laser system which provides more than 1.5W of narrowband light, tunable in the range from 455-463 nm. It consists of a commercial Titanium-Sapphire laser whi…
Uncovering the non-equilibrium phase structure of an open quantum spin system
S. Helmrich, A. Arias, S. Whitlock
We experimentally and theoretically investigate the non-equilibrium phase structure of a well-controlled driven-disspative quantum spin system governed by the interplay of coherent…
Two-body interactions and decay of three-level Rydberg-dressed atoms
S. Helmrich, A. Arias, N. Pehoviak +1
We theoretically analyze the interactions and decay rates for atoms dressed by multiple laser fields to strongly interacting Rydberg states using a quantum master equation approach…
Observation of Efimov Resonances in a Mixture with Extreme Mass Imbalance
R. Pires, J. Ulmanis, S. Häfner +4
We observe two consecutive heteronuclear Efimov resonances in an ultracold Li-Cs mixture by measuring three-body loss coefficients as a function of magnetic field near a Feshbach r…
