Low overhead universality and quantum supremacy using only Z control
We consider a model of quantum computation we call “varying Z” (VZ), defined by applying controllable Z-diagonal Hamiltonians in the presence of a uniform and constant external X field, and prove that it is universal, even in one dimension. Universality is demonstrated by construction of a universal...
