Fundamental bound on Wigner negativity generation from environmental collisions
Isaac Layton, Takahiro Sagawa, Ken Funo
Beyond quadratic potentials, classical evolution laws are typically thought to arise from quantum theory as an approximate description. Here we show that classical evolution laws c…
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…
Stochastic Thermodynamics on Time-Evolving Curved Spaces
Rihito Nagase, Shoki Sugimoto, Asuka Takatsu +1
We construct stochastic thermodynamics of overdamped Langevin systems on nonrelaticvistic curved spaces with time-dependent metrics. The time dependence of the metric contributes t…
Stochastic Thermodynamics for Autoregressive Generative Models: A Non-Markovian Perspective
Takahiro Sagawa
Autoregressive generative models -- including Transformers, recurrent neural networks, classical Kalman filters, state space models, and Mamba -- all generate sequences by sampling…
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…
A levitated nano-accelerometer sensitized by quantum quench
M. Kamba, S. Otabe, K. Funo +2
We realize a nanoscale accelerometer exploiting the nonequilibrium dynamics of a nanoparticle near the quantum ground state. We explore the dynamics after quenching the trapping po…
