Localization and coherent control of 25 nuclear spins in Silicon Carbide
Pierre Kuna, Erik Hesselmeier-Hüttmann, Phillip Schillinger +7
Optically addressable spin defects are excellent candidate platform for quantum sensing and quantum network. Nuclear spins coupled to color centers naturally enable long lived quan…

Measuring nuclear spin qubits by qudit-enhanced spectroscopy in Silicon Carbide
Erik Hesselmeier, Pierre Kuna, István Takács +8
Nuclear spins with hyperfine coupling to single electron spins are highly valuable quantum bits. In this work we probe and characterise the particularly rich nuclear spin environme…

Accurate Hyperfine Tensors for Solid State Quantum Applications: Case of the NV Center in Diamond
István Takács, Viktor Ivády
The decoherence of point defect qubits is often governed by the electron spin-nuclear spin hyperfine interaction that can be parameterized by using ab inito calculations in princip…
