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…
Adversarial Thermodynamics
Maite Arcos, Philippe Faist, Takahiro Sagawa +1
In thermodynamics, an agent's ability to extract work is fundamentally constrained by their environment. Traditional frameworks struggle to capture how strategic decision-making un…
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…
Thermodynamic optimization of finite-time feedback protocols for Markov jump systems
Rihito Nagase, Takahiro Sagawa
In recent advances in finite-time thermodynamics, optimization of entropy production required for finite-time information processing is an important issue. In this work, we conside…
Experimentally achieving minimal dissipation via thermodynamically optimal transport
Shingo Oikawa, Yohei Nakayama, Sosuke Ito +2
Optimal transport theory, originally developed in the 18th century for civil engineering, has since become a powerful optimization framework across disciplines, from generative AI…
Thermodynamic approach to quantum cooling limit of continuous Gaussian feedback
Kousuke Kumasaki, Toshihiro Yada, Ken Funo +1
Feedback cooling plays a critical role in stabilizing quantum systems and achieving low temperatures, where a key question is to determine the fundamental thermodynamic limits on c…
