Unified entropy production in finite quantum systems
Tomohiro Nishiyama, Yoshihiko Hasegawa
In finite-dimensional quantum systems, temperature cannot be uniquely defined. This, in turn, implies that there are several ways to define entropy production in finite-dimensional…
Quantum thermodynamic uncertainty relations without quantum corrections: A coherent-incoherent correspondence approach
Tomohiro Nishiyama, Yoshihiko Hasegawa
We introduce the coherent-incoherent correspondence as a framework for deriving quantum thermodynamic uncertainty relations under continuous measurement in Lindblad dynamics. The c…
Thermodynamic entropic uncertainty relation
Yoshihiko Hasegawa, Tomohiro Nishiyama
Thermodynamic uncertainty relations reveal a fundamental trade-off between the precision of a trajectory observable and entropy production, where the uncertainty of the observable…
A unified framework of unitarily residual measures for quantifying dissipation
Tomohiro Nishiyama, Yoshihiko Hasegawa
Open quantum systems are governed by both unitary and non-unitary dynamics, with dissipation arising from the latter. Traditional quantum divergence measures, such as quantum relat…
