Adptive quantum computation, constant depth quantum circuits and arthur-merlin games
Abstract
We present evidence that there exist quantum computations that can be carried out in constant depth, using 2-qubit gates, that cannot be simulated classically with high accuracy. We prove that if one can simulate these circuits classically efficiently then BQP ⊆ AM.
