Recent years have seen tremendous progress in the theoretical understanding of quantum
systems driven dissipatively by coupling to different baths at their edges. This was possible …

Two fundamental ingredients play a decisive role in the foundation of fluctuation relations:
the principle of microreversibility and the fact that thermal equilibrium is described by the …

Continuously measured quantum systems are characterized by an output current, in the form
of a stochastic and correlated time series, which conveys crucial information about the …

The canonical example of a quantum-mechanical two-level system is spin. The simplest
picture of spin is a magnetic moment pointing up or down. The full quantum properties of …

In contrast to the spatial Bell's inequalities which probe entanglement between spatially
separated systems, the Leggett–Garg inequalities test the correlations of a single system …

Fluctuation theorems (FTs), which describe some universal properties of nonequilibrium
fluctuations, are examined from a quantum perspective and derived by introducing a two …

We consider the speed limit for classical stochastic Markov processes with and without the
local detailed balance condition. We find that, for both cases, a trade-off inequality exists …

We review recent theoretical work on thermoelectric energy harvesting in multi-terminal
quantum-dot setups. We first discuss several examples of nanoscale heat engines based on …

We report high-bandwidth charge sensing measurements using a GaAs quantum point
contact embedded in a radio frequency impedance matching circuit (rf-QPC). With the rf …

Transport in a quantum point contact (QPC) can be used to generate many-body
entanglement of Fermi seas in the leads. A universal relation is found between the …
