Coupling nitrogen-vacancy centers in diamond in superconducting flux Qubits. Physical Review Letters 105(21): 210501.0031-9007http://nrs.harvard.edu/urn-3:HUL.InstRepos:8919556We propose a method to achieve coherent coupling between nitrogen-vacancy (NV) centers in diamond and superconducting (SC) flux qubits. The resulting coupling can be used to create a coherent interaction between the spin states of distant NV centers mediated by the flux qubit. Furthermore, the magnetic coupling can be used to achieve a coherent transfer of quantum information between the flux qubit and an ensemble of NV centers. This enables a long-term memory for a SC quantum processor and possibly an interface between SC qubits and light.en-USJournal Article2012-06-2510.1103/PhysRevLett.105.210501
