![]() ![]() But having done that, how do we then unravel the higher levels of the counting hierarchy? For example, how do we simulate PP PP in PP BQP=PP? We don’t have any mechanism to pass the quantum advice up to the oracle PP machine, since queries to a PP oracle are by definition classical strings. We can then verify that the advice state works to solve PP problems, by using (for example) the interactive protocol for the permanent, or some other #P-complete problem. The issue is this: in QMA, we can indeed nondeterministically guess an (amplified) quantum advice state for a BQP/qpoly algorithm. If PP is in BQP/qpoly, then certainly P #P=PP=QMA, but I don’t know how to collapse any further levels of the counting hierarchy. But on further reflection, I only know how to show a collapse of the counting hierarchy under the stronger assumption that PP is in BQP/poly. (1) In my 2006 paper “ Oracles are subtle but not malicious,” I claimed to show that if PP is contained in BQP/qpoly, then the counting hierarchy collapses to QMA (Theorem 5).
