Registering my uneducated guess: Is this implying there was previously hope you could trap a hot system in a Gibbs state and demonstrate nice stable quantum supremacy with those, but they found hot Gibbs states are necessarily all boring and decohered after all?
- hughesjj 2y agoI believe so, from abstract > A priori the task of preparing a Gibbs state is a natural candidate for achieving super-polynomial quantum speedups, but our results rule out this possibility above a fixed constant temperature.
