Blueprint of a scalable spin qubit shuttle device for coherent mid-range qubit transfer in disordered Si/SiGe/SiO
Veit Langrock, Jan A. Krzywda, Niels Focke +3
Silicon spin qubits stand out due to their very long coherence times, compatibility with industrial fabrication, and prospect to integrate classical control electronics. To achieve…
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…
