The problem 2-LOCAL HAMILTONIAN has been shown to be complete for the quantumcomputational class QMA [1]. In this paper we show that this important problemremains QMA-complete when the interactions of the 2-local Hamiltonian are betweenqubits on a two-dimensional (2-D) square lattice. Our results are partially derived withnovel perturbation gadgets that employ mediator qubits which allow us to manipulatek-local interactions. As a side result, we obtain that quantum adiabatic computationusing 2-local interactions restricted to a 2-D square lattice is equivalent to the circuitmodel of quantum computation. Our perturbation method also shows how any stabilizerspace associated with a k-local stabilizer (for constant k) can be generated as anapproximate ground-space of a 2-local Hamiltonian.
