In quantum physics, we usually face exponentially large degrees of freedom and the large-scale data obtained from quantum systems, which constantly defy our analysis capability. Here, we sketch how machine learning may become a valuable tool in overcoming huge amounts of data and degrees of freedom and reverse thinking, which builds a meaningful bridge between computation power and physical intuition. We outline our recent developments on efficient and general algorithms based upon machine learning for quantum compiling and ground-state properties of quantum many-body Hamiltonians, which provide a new perspective for intriguing applications of machine learning in quantum physics.
