Abstract

Simple constructions and protocols are demonstrated to allow the implementation of universal quantum computation on an arbitrarily large quantum system by controlling a fixed number of spins, vastly reducing the engineering requirements in comparison to a direct implementation of the circuit model. Analytic pulse sequences are derived for deterministic gate operation and system cooling which only require pulse strengths that are comparable to the intrinsic Hamiltonian of the system.
