Scalable arrangements of nitrogen vacancy centers (NV) in diamond remain an open key challenge on the way to efficient quantum information processing, quantum simulation and magnetic sensing applications at the quantum limit. Here we provide a solution for creating a scalable system of individually addressable NV centers based on the self-assembling capabilities of biological systems in combination with the bridging of the bio-nano interface by means of surface functionalized nanodiamonds. We provide a detailed theoretical analysis on the feasibility of multiqubit quantum operations in such systems, exploiting the significant dipolar coupling on the nanometer scale and address the problems of decoherence, imperfect couplings and the randomness of the NV symmetry axes. We show that this allows for the high-fidelity creation of entanglement, cluster states and quantum simulation applications. In addition we present the first experimental demonstration of connecting nanodiamonds with biological systems (SP1 complexes).
