Hunting for quantum-classical crossover in condensed matter problems
Nobuyuki Yoshioka, Tsuyoshi Okubo, Yasunari Suzuki +2
The intensive pursuit for quantum advantage in terms of computational complexity has further led to a modernized crucial question: {\it When and how will quantum computers outperfo…
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…
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…
