Abstract
A class of lazy two-qubit Hamiltonians, those which can simulate themselves faster with the aid of fast local control than with uninterrupted evolution was defined. When a lazy Hamiltonian was used in the time-optimal simulation of any nonlocal two-qubit unitary, a simulation which will require an infinite number of steps, and thus will be impractical was shown. A simple set of sufficient conditions enabling to prove that a given Hamiltonian was lazy was derived.
