High fidelity optical readout of a nuclear spin qubit in Silicon Carbide
Erik Hesselmeier, Oliver von Berg, Pierre Kuna +7
Quantum state readout is a key requirement for a successful qubit platform. In this work we demonstrate a high fidelity quantum state readout of a V2 center nuclear spin based on a…
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…
Spectral stability of V2 centres in sub-micron 4H-SiC membranes
Jonah Heiler, Jonathan Körber, Erik Hesselmeier +9
Colour centres in silicon carbide emerge as a promising semiconductor quantum technology platform with excellent spin-optical coherences.However, recent efforts towards maximising…
