Optimal work extraction from quantum states by photo-assisted Cooper pair tunneling
Niels Lörch, Christoph Bruder, Nicolas Brunner +1
The theory of quantum thermodynamics predicts fundamental bounds on work extraction from quantum states. As these bounds are derived in a very general and abstract setting, it is u…
Markovian master equations for quantum thermal machines: local vs global approach
Patrick P. Hofer, Martí Perarnau-Llobet, L. David M. Miranda +4
The study of quantum thermal machines, and more generally of open quantum systems, often relies on master equations. Two approaches are mainly followed. On the one hand, there is t…
Quantum Thermal Machine as a Thermometer
Patrick P. Hofer, Jonatan Bohr Brask, Martí Perarnau-Llobet +1
We propose the use of a quantum thermal machine for low-temperature thermometry. A hot thermal reservoir coupled to the machine allows for simultaneously cooling the sample while d…
Quasi-probability distributions for observables in dynamic systems
Patrick P. Hofer
We develop a general framework to investigate fluctuations of non-commuting observables. To this end, we consider the Keldysh quasi-probability distribution (KQPD). This distributi…
On-demand entanglement generation using dynamic single-electron sources
Patrick P. Hofer, David Dasenbrook, Christian Flindt
We review our recent proposals for the on-demand generation of entangled few-electron states using dynamic single-electron sources. The generation of entanglement can be traced bac…
Autonomous Quantum Refrigerator in a Circuit-QED Architecture Based on a Josephson Junction
Patrick P. Hofer, Martí Perarnau-Llobet, Jonatan Bohr Brask +3
An implementation of a small quantum absorption refrigerator in a circuit QED architecture is proposed. The setup consists of three harmonic oscillators coupled to a Josephson unct…
