While quantum computers have strong potential for quantum-many-body simulations, demonstrating an advantage for systems of practical relevance is still a challenge. Here, the authors show that quantum computers can efficiently sample thermal states of weakly and strongly interacting fermions – which is notoriously hard for classical Monte Carlo methods due to the fermionic sign problem.
