Second law of thermodynamics is ingrained within quantum mechanics

Results in Physics, 2018
We show that the second law of thermodynamics is rooted in quantum mechanics, inasmuch as allowing the substitution of the Boltzmann constant k and temperature with respectively the Planck constant and quantum numbers. In particular, we will see that the

Thermodynamic uncertainty relation for quantum entropy production [PDF]

arXiv
In quantum thermodynamics, entropy production is usually defined in terms of the quantum relative entropy between two states. We derive a lower bound for the quantum entropy production in terms of the mean and variance of quantum observables, which we will refer to as a thermodynamic uncertainty relation (TUR) for the entropy production. In the absence

Universal validity of the second law of information thermodynamics

npj Quantum Information
Adiabatic measurements, followed by feedback and erasure protocols, have often been considered as a model to embody Maxwell’s Demon paradox and to study the interplay between thermodynamics and information processing.

Fluctuation and inertia

Nuclear Physics B, 2020
How the principle of inertia survives quantum fluctuations is an interesting question. Smolin has proposed a hypothesis that quantum fluctuations are in fact real statistical fluctuations.

Quantum Thermodynamics [PDF]

arXiv
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 fundamentally unavoidable. These lecture notes provide an introduction to the thermodynamics of small quantum systems.

Fidelity-dissipation relations in quantum gates

Physical Review Research
Accurate quantum computing relies on the precision of quantum gates. However, quantum gates in practice are generally affected by dissipative environments, which can significantly reduce their fidelity.
