Implementation of quantum error correction protocols in a small quantum register — •Matthias Nitsche, Matthias Steiner, Gerald Waldherr, Philipp Neumann, Fedor Jelezko, and Joerg Wrachtrup — 3. Physikalisches Institut, Universitaet Stuttgart, Pfaffenwaldring 57, D-70550, Germany

Electron spins associated with the nitrogen-vacancy (NV) defect in diamond are promising candidates for quantum information processing at room temperature. For practical applications, however, the quantum information stored in a spin qubit has to be protected from phase and bit-flip errors. Techniques like the encoding of quantum state in decoherence free subspaces or the application of error correction protocols involving proximal nuclear spins are discussed.
