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…
Thermodynamic Uncertainty Relations for Steady-State Thermodynamics
Takuya Kamijima, Sosuke Ito, Andreas Dechant +1
A system can be driven out of equilibrium by both time-dependent and nonconservative forces, which gives rise to a decomposition of the dissipation into two non-negative components…
Deep reinforcement learning for preparation of thermal and prethermal quantum states
Shotaro Z. Baba, Nobuyuki Yoshioka, Yuto Ashida +1
We propose a method based on deep reinforcement learning that efficiently prepares a quantum many-body pure state in thermal or prethermal equilibrium. The main physical intuition…
