Title: Thermodynamic Reverse Bounds for General Open Quantum Processes
Authors: Francesco Buscemi, Daichi Fujiwara, Naoki Mitsui, Marcello Rotondo
Abstract summary: Various quantum thermodynamic bounds are shown to stem from a single tighter and more general inequality, consequence of the operator concavity of the logarithmic function. We apply our bound to evaluate the thermodynamic length for open processes, the heat exchange in erasure processes, and the maximal energy outflow in general quantum evolutions.

Abstract: Various quantum thermodynamic bounds are shown to stem from a single tighter and more general inequality, consequence of the operator concavity of the logarithmic function. Such an inequality, which we call the "thermodynamic reverse bound", is compactly expressed as a quantum relative entropy, from which it inherits mathematical properties and meaning. As concrete examples, we apply our bound to evaluate the thermodynamic length for open processes, the heat exchange in erasure processes, and the maximal energy outflow in general quantum evolutions.

Thermodynamic uncertainty relation for quantum entropy production [0.0]
In quantum thermodynamics, entropy production is usually defined in terms of the quantum relative entropy between two states. In the absence of coherence between the states, our result reproduces classic TURs in thermodynamics.

Thermodynamics of adiabatic quantum pumping in quantum dots [50.24983453990065]
We consider adiabatic quantum pumping through a resonant level model, a single-level quantum dot connected to two fermionic leads. We develop a self-contained thermodynamic description of this model accounting for the variation of the energy level of the dot and the tunnelling rates with the thermal baths.

Relating Heat and Entanglement in Strong Coupling Thermodynamics [0.0]
We develop a new approach to study thermodynamics in the strong coupling regime. We apply the method to calculate the time-dependent thermodynamic properties of a system and an environment. The results indicate that the transient imbalance between heat dissipated and heat absorbed is responsible for the generation of system-environment entanglement.

Catalytic Transformations of Pure Entangled States [62.997667081978825]
Entanglement entropy is the von Neumann entropy of quantum entanglement of pure states. The relation between entanglement entropy and entanglement distillation has been known only for the setting, and the meaning of entanglement entropy in the single-copy regime has so far remained open. Our results imply that entanglement entropy quantifies the amount of entanglement available in a bipartite pure state to be used for quantum information processing, giving results an operational meaning also in entangled single-copy setup.
