Enhancing the power of a quantum heat engine via control of the system--reservoir coupling
Sabrina Burgardt, Julian Feß, Silvia Hiebel +2
The non-equilibrium properties of open quantum systems are determined by the microscopic laws governing energy exchange with their environment. In particular, an enhancement of the…

Quantum-enabled active matter at the atomic scale
Sabrina Burgardt, Julian Feß, Alexander Guthmann +8
Active matter comprises particles that extract energy from their local environment and convert it into motion. Although active particles have been miniaturized down to the nanoscal…

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…
