We propose and analyze an architecture for a scalable, solid-state quantum information processor capable of operating at or near room temperature. Our approach is based upon recent experimental advances involving Nitrogen-Vacancy color centers in diamond. The architecture involves a hierarchy of control at successive length scales and makes use of nuclear-spin quantum memory and dark-spin chains to couple different NV senters. The architecture is applicable to realistic conditions which include disorder and relevant decoherence mechanisms.
