Optimal Two-Qubit Gates for Group-IV Color-Centers in Diamond
Jurek Frey, Katharina Senkalla, Philipp J. Vetter +3
Color centers associated with group-IV dopants in diamond with long-lived nuclear spins have emerged as major candidates for distributed quantum computing nodes and quantum repeate…
High-Fidelity Single-Shot Readout and Selective Nuclear Spin Control for a Spin-1/2 Quantum Register in Diamond
Prithvi Gundlapalli, Philipp J. Vetter, Genko Genov +5
Quantum networks offer a way to overcome the size and complexity limitations of single quantum devices by linking multiple nodes into a scalable architecture. Group-IV color center…
Coherent Control of a Long-Lived Nuclear Memory Spin in a Germanium-Vacancy Multi-Qubit Node
Nick Grimm, Katharina Senkalla, Philipp J. Vetter +6
The ability to process and store information on surrounding nuclear spins is a major requirement for group-IV color center-based repeater nodes. We demonstrate coherent control of…
Transform-Limited Photon Emission From a Lead-Vacancy Center in Diamond Above 10 K
Peng Wang, Lev Kazak, Katharina Senkalla +9
Transform-limited photon emission from quantum emitters is essential for high-fidelity entanglement generation. In this study, we report the coherent optical property of a single n…
Germanium Vacancy in Diamond Quantum Memory Exceeding 20 ms
Katharina Senkalla, Genko Genov, Mathias H. Metsch +2
Negatively charged group-IV defects in diamond show great potential as quantum network nodes due to their efficient spin-photon interface. However, reaching sufficiently long coher…
Initialization and Readout of Nuclear Spins via negatively charged Silicon-Vacancy Center in Diamond
Mathias H. Metsch, Katharina Senkalla, Benedikt Tratzmiller +7
In this work, we demonstrate initialization and readout of nuclear spins via a negatively charged silicon-vacancy (SiV) electron spin qubit. Under Hartmann-Hahn conditions the elec…
Universality of local weak interactions and its application for interferometric alignment
Jan Dziewior, Lukas Knips, Demitry Farfurnik +7
The modification of the effect of interactions of a particle as a function of its pre- and postselected states is analyzed theoretically and experimentally. The universality proper…
