“…The simplest of these complete problems is the 2-local Hamiltonian problem, which is informally the quantum version of the circuit satisfiability problem for unitary circuits with gates of constant size. A formal description of this problem, as well as a proof that the 5-local Hamiltonian problem is QMA-complete can be found in [10]. The improvement of this result to the 2-local case is due to Kempe, Kitaev, and Regev [8].…”

“…Another fact is that the unpublished proof by Kitaev and Watrous for the upper bound PP of the class QMA of problems having single-proof quantum Merlin-Arthur proof systems no longer works well for the multi-proof cases with the most straightforward modification. The simplified proof by Marriott and Watrous [39] for the same statement and even the proof of QMA ⊆ PSPACE [30,31] are also the cases. Furthermore, the existing proofs for the property that parallel repetition of a single-proof system reduces the error probability to be arbitrarily small [32,48,31,39] cannot be applied to the multi-proof cases.…”

Furthermore, the existing proofs for the property that parallel repetition of a single-proof system reduces the error probability to be arbitrarily small [32,48,31,39] cannot be applied to the multi-proof cases. Of course, these arguments do not imply that using multiple quantum proofs is more powerful than using only a single quantum proof from the complexity theoretical viewpoint.…”

“…The first QMA-complete Hamiltonian was introduced by Kitaev [11] building on ideas of Feynman [7]. The Hamiltonian construction represents an updated version of the Cook-Levin construction which shows any NP-complete problem can be embedded into the Boolean satisfiability problem [21].…”
