Work extractability from energy eigenstates under optimized local operations
Shotaro Z. Baba, Nobuyuki Yoshioka, Takahiro Sagawa
We examine the relationship between the second law of thermodynamics and the energy eigenstates of quantum many-body systems that undergo cyclic unitary evolution. Using a numerica…
Nonlinearity-induced topological phase transition characterized by the nonlinear Chern number
Kazuki Sone, Motohiko Ezawa, Yuto Ashida +2
As first demonstrated by the characterization of the quantum Hall effect by the Chern number, topology provides a guiding principle to realize robust properties of condensed matter…
Thermodynamically Optimal Information Gain in Finite Time Measurement
Rihito Nagase, Takahiro Sagawa
The tradeoff relation between speed and cost is a central issue in designing fast and efficient information processing devices. We derive an achievable bound on thermodynamic cost…
Thermodynamics of Information
Juan M. R. Parrondo
As early as 1867, two years after the introduction of the concept of entropy by Clausius, Maxwell showed that the limitations imposed by the second law of thermodynamics depend on…
Role of Topology in Relaxation of One-Dimensional Stochastic Processes
Taro Sawada, Kazuki Sone, Ryusuke Hamazaki +2
Stochastic processes are commonly used models to describe dynamics of a wide variety of nonequilibrium phenomena ranging from electrical transport to biological motion. The transit…
Universal cost bound of quantum error mitigation based on quantum estimation theory
Kento Tsubouchi, Takahiro Sagawa, Nobuyuki Yoshioka
We present a unified approach to analyzing the cost of various quantum error mitigation methods on the basis of quantum estimation theory. By analyzing the quantum Fisher informati…
