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…
Measuring the environment of a Cs qubit with dynamical decoupling sequences
Sabrina Burgardt, Simon B. Jäger, Julian Feß +3
We report the experimental implementation of dynamical decoupling on a small, non-interacting ensemble of up to 25 optically trapped, neutral Cs atoms. The qubit consists of the tw…
Impact of Charge Conversion on NV-Center Relaxometry
Isabel Cardoso Barbosa, Jonas Gutsche, Artur Widera
Relaxometry schemes employing nitrogen-vacancy (NV) centers in diamonds are essential in biology and physics to detect a reduction of the color centers' characteristic spin relaxat…
Power of a quasi-spin quantum Otto engine at negative effective temperature
Jens Nettersheim, Sabrina Burgardt, Quentin Bouton +3
Heat engines usually operate by exchanging heat with thermal baths at different (positive) temperatures. Nonthermal baths may, however, lead to a significant performance boost. We…
Sensitivity of a collisional single-atom spin probe
Jens Nettersheim, Quentin Bouton, Daniel Adam +1
We study the sensitivity of a collisional single-atom probe for ultracold gases. Inelastic spin-exchange collisions map information about the gas temperature T or external magnetic…
Coherent and dephasing spectroscopy for single-impurity probing of an ultracold bath
Daniel Adam, Quentin Bouton, Jens Nettersheim +2
We report Ramsey spectroscopy on the clock states of individual Cs impurities immersed in an ultracold Rb bath. We record both the interaction-driven phase evolution and the decay…
