Violating the Thermodynamic Uncertainty Relation in the Three-Level Maser
Alex Arash Sand Kalaee, Andreas Wacker, Patrick P. Potts
Nanoscale heat engines are subject to large fluctuations which affect their precision. The Thermodynamic Uncertainty Relation (TUR) provides a trade-off between output power, fluct…
Hybrid Thermal Machines: Generalized Thermodynamic Resources for Multitasking
Gonzalo Manzano, Rafael Sánchez, Ralph Silva +4
Thermal machines perform useful tasks--such as producing work, cooling, or heating--by exchanging energy, and possibly additional conserved quantities such as particles, with reser…
Quantum teleportation of single-electron states
Edvin Olofsson, Peter Samuelsson, Nicolas Brunner +1
We consider a scheme for on-demand teleportation of a dual-rail electron qubit state, based on single-electron sources and detectors. The scheme has a maximal efficiency of 25%, wh…
Tight bound on finite-resolution quantum thermometry at low temperatures
Mathias R. Jørgensen, Patrick P. Potts, Matteo G. A. Paris +1
Precise thermometry is of wide importance in science and technology in general and in quantum systems in particular. Here, we investigate fundamental precision limits for thermomet…
Introduction to Quantum Thermodynamics (Lecture Notes)
Patrick P. Potts
The theory of quantum thermodynamics investigates how the concepts of heat, work, and temperature can be carried over to the quantum realm, where fluctuations and randomness are fu…
Certifying Non-Classical Behavior for Negative Keldysh Quasi-Probabilities
Patrick P. Potts
We introduce an experimental test for ruling out classical explanations for the statistics obtained when measuring arbitrary observables at arbitrary times using individual detecto…
