Speed limit for open quantum systems
Ken Funo, Naoto Shiraishi, Keiji Saito
We study the quantum speed limit for open quantum systems described by the Lindblad master equation. The obtained inequality shows a trade-off relation between the operation time a…
Path integral approach to heat in quantum thermodynamics
Ken Funo, H. T. Quan
We study the heat statistics of a quantum Brownian motion described by the Caldeira-Leggett model. By using the path integral approach, we introduce a novel concept of the quantum…
Quantum Fluctuation Theorems
Ken Funo, Masahito Ueda, Takahiro Sagawa
Recent advances in experimental techniques allow one to measure and control systems at the level of single molecules and atoms. Here gaining information about fluctuating thermodyn…
Speed Limit for Classical Stochastic Processes
Naoto Shiraishi, Ken Funo, Keiji Saito
Speed limit for classical stochastic Markov processes with discrete states is studied. We find that a trade-off inequality exists between the speed of the state transformation and…
