Quantum enhancement of information-mediated energy transfer
Shotaro Oki, Yuki Kadono, Kaito Tojo +2
Thermodynamics of information identifies information flow as a thermodynamic resource, but whether quantum coherence and collective coupling can enhance it at low entropy-productio…
Thermodynamic uncertainty relation under continuous measurement and feedback with quantum-classical-transfer entropy
Kaito Tojo, Takahiro Sagawa, Ken Funo
We derive a thermodynamic uncertainty relation (TUR) under quantum continuous measurement and feedback control. By incorporating the quantum-classical-transfer entropy, which quant…
Optimizing optimal transport: Role of final distributions in finite-time thermodynamics
Kaito Tojo, Rihito Nagase, Ken Funo +1
Performing thermodynamic tasks within finite time while minimizing thermodynamic costs is a central challenge in stochastic thermodynamics. Here, we develop a unified framework for…
Thermodynamic uncertainty relation for feedback cooling
Kousuke Kumasaki, Kaito Tojo, Takahiro Sagawa +1
Feedback cooling enables a system to achieve low temperatures through measurement-based control. Determining the thermodynamic cost required to achieve the ideal cooling efficiency…
Optimal Finite-time Maxwell's Demons in Langevin Systems
Takuya Kamijima, Asuka Takatsu, Ken Funo +1
We identify the optimal protocols to achieve the minimal entropy production in finite-time information exchange processes in Langevin systems, on the basis of optimal transport the…
Finite-time thermodynamic bounds and tradeoff relations for information processing
Takuya Kamijima, Ken Funo, Takahiro Sagawa
In thermal environments, information processing requires thermodynamic costs determined by the second law of thermodynamics. Information processing within finite time is particular…
