The nitrogen vacancy (NV) center in diamond is a promising candidate to realize quantum networks consisting of multi-qubit nodes optically linked over large distances.In this talk,I will outline our recent progress towards this goal.First,I will present how multi-qubit nodes can be formed using the NV electron spin to control and entangle nuclear spins in its environment.As a demonstration I will present the realization of a basic quantum error correction protocol [1].Second,we will discuss the unconditional quantum teleportation of a nuclear spin to an electron spin in another diamond 3 meters away [2,3].Together these results provide the basis for establishing quantum networks based on spins in diamond.
