Quantum error correction for quantum registers based on color centers — •Daniel Dulog and Martin Plenio — Universität Ulm, Institut für Theoretische Physik, Ulm, Germany

Among many quantum technologies, color centers in diamond provide a possible hardware basis for quantum computation, where a typical information processing unit might contain several nitrogen-vacancy (NV) centers in contact with adjacent carbon-13 nuclear spins. With specifically tailored dynamical decoupling sequences (PRL 117, 130502) it is possible to execute selective, high-fidelity two-body gates between the electron spin of the NV center and a targeted nuclear spin. We present a protocol that uses speed-optimized gates of that kind to utilize the nuclear spin environment as code space for quantum error correction within the NV center qubit register.
