Nuclear spins and electron spins in molecules have relatively long decoherence times, offer appropriate interactions for use in quantum gate operations, and can be controlled using magnetic resonance techniques. In this chapter, from the viewpoint of using these spins for quantum information processing, Hamiltonian engineering methods and hardware are developed for hyper precision control. Additionally, hyperpolarization techniques are developed for spin initialization, and a spin amplification method is developed for detection.
