Acoustic phonons, spin-phonon coupling and spin relaxation via the lattice reorientation mechanism in hexagonal germanium nanowires
Baksa Kolok, György Frank, András Pályi
Spin relaxation via electron-phonon interaction is an important decoherence mechanism for spin qubits. In this work, we study spin relaxation in hexagonal (2H) germanium, a novel d…
Multi-shot readout error benchmark of the nitrogen-vacancy center's electronic qubit
Péter Boross, Domonkos Svastits, GyÅzÅ Egri +1
The ground-state electronic spin of a negatively charged nitrogen-vacancy center in diamond can be used for room-temperature experiments showing coherent qubit functionality. At ro…
Readout sweet spots for spin qubits with strong spin-orbit interaction
Domonkos Svastits, Bence Hetényi, Gábor Széchenyi +4
Qubit readout schemes often deviate from ideal projective measurements, introducing critical issues that limit quantum computing performance. In this work, we model charge-sensing-…
Limitations of the -tensor formalism of semiconductor spin qubits
Zoltán György, András Pályi, Gábor Széchenyi
The -tensor formalism is a powerful method for describing the electrical driving of semiconductor spin qubits. However, up to now, this technique has only been applied to the si…
