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…
