Matchgate and space-bounded quantum computations are equivalent
... computations that use a restricted class of gates or computational steps (that are generally not fully universal) e.g. computations with Clifford gates [3, 2] or with nearest-neighbour matchgates [4, 6, 1]. (The term “nearest-neighbour” here refers to the requirement that the matchgates act only on ...
