A reset-if-leaked procedure for encoded spin qubits
Veit Langrock, David P. DiVincenzo
We report a substantially simplified procedure, based on group-theoretic reasoning, for the reduction of qubit leakage in exchange-only spin qubits. We to find exchange sequences w…

Towards a realistic GaAs-spin qubit device for a classical error-corrected quantum memory
Manuel Rispler, Pascal Cerfontaine, Veit Langrock +1
Based on numerically-optimized real-device gates and parameters we study the performance of the phase-flip (repetition) code on a linear array of Gallium Arsenide (GaAs) quantum do…

Large, tunable valley splitting and single-spin relaxation mechanisms in a Si/SiGe quantum dot
Arne Hollmann, Tom Struck, Veit Langrock +8
Valley splitting is a key figure of silicon-based spin qubits. Quantum dots in Si/SiGe heterostructures reportedly suffer from a relatively low valley splitting, limiting the opera…
