The realization of a scalable quantum information processor has emerged over the past decade as one of the central challenges at the interface of fundamental science and engineering. In this talk, I will describe 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. In particular, we demonstrate that the multiple challenges associated with operation at ambient temperature, individual addressing at the nanoscale, strong qubit coupling, robustness against disorder and low decoherence rates can be simultaneously achieved under realistic, experimentally relevant conditions. The architecture uses a novel approach to spin-chain based quantum information transfer and includes a hierarchy of control at successive length scales.
