【题  目】Quantum-classical hybrid Monte Carlo 

【摘  要】In this talk, I will present recent progress in quantum simulation algorithms. Combining classical-computing quantum Monte Carlo methods with quantum comping allows us to simulate the time evolution and solve the ground state problems of quantum many-body systems, with the sign problem eased or even removed. We will find that such quantum-classical hybrid algorithms can outperform classical algorithms even on noisy quantum computers. We show that randomising quantum circuits is a systematic way of increasing the expressibility in quantum computing.
