Accurate and efficient quantum Gibbs state preparation

Abstract：

Preparing Gibbs state on quantum computer is an essential task for quantum algorithm, which is believed to be one of the natural candidates for quantum advantage. Efforts to generalize classical gibbs sampler to quantum come to a remarkable result, the first implementable quantum Gibbs sampler recently[CKBG23][CKG23]. The speaker will review these works, together with [JI24] which provides an alternative Gibbs sampler.
