Hybridization: When two wrongs make a right

The development of quantum information enabled technologies has reached an interesting stage where we can now in principle engineer composite systems to exploit the best properties of these individual systems. Hybridization potentially allows us to undertake operations and tasks that may otherwise prove difficult. Such an example occurs where we couple a superconducting circuit to an electron spin (or ensemble). We show in this presentation how the coherence properties of single electron spins (or ensembles) can be dramatically increased just by it coupling with the superconducting qubit, that is two systems with limited coherence properties can form a combined system with a much longer coherence time.
