Quantum information processing with nuclear spins in diamond
Spins associated to defects in solids are promising qubits for quantum information processing. We have developed novel control gates for an electron spin coupled to nuclear spins, and applied this scheme to realise a universally connected 10-qubit register using an NV-centre in diamond [1]. Moreover, we employed dynamical decoupling of the register to realise coherence times up to 63(2) seconds. Building upon these techniques, we have also recently demonstrated the 3D imaging of a system of 27 coupled nuclear spins with atomic scale resolution [2].
