Nuclear spin control with highly strained silicon-vacancy centers — •Marco Klotz, Andreas Tangemann, and Alexander Kubanek — nstitute for Quantum Optics, University Ulm, Germany

Spin qubits in solid state hosts are due to their promise of scalability candidates for the realization of quantum networks. The good spin properties of diamond paired with the optical properties of group-IV defects make them of special interest. We are using highly strained silicon vacancy centers to mitigate phonon induced electron spin dephasing at liquid Helium temperature. Here we show our current results on electron spin characterization. Furthermore, we use highly efficient electron spin driving to access, control and characterize coupled C13 nuclear spins. This paves the way for nuclear spin assisted quantum error correction and networking with group IV defects.
