Closed-loop control of a GaAs-based singlet-triplet spin qubit with 99.5% gate fidelity and low leakage
Pascal Cerfontaine, Tim Botzem, Julian Ritzmann +6
Semiconductor spin qubits have recently seen major advances in coherence time and control fidelities, leading to a single-qubit performance that is on par with other leading qubit…
Self-Consistent Calibration of Quantum Gate Sets
Pascal Cerfontaine, René Otten, Hendrik Bluhm
The precise and automated calibration of quantum gates is a key requirement for building a reliable quantum computer. Unlike errors from decoherence, systematic errors can in princ…
A Machine Learning Approach for Automated Fine-Tuning of Semiconductor Spin Qubits
Julian D. Teske, Simon Humpohl, René Otten +6
While spin qubits based on gate-defined quantum dots have demonstrated very favorable properties for quantum computing, one remaining hurdle is the need to tune each of them into a…
High-fidelity gate set for exchange-coupled singlet-triplet qubits
Pascal Cerfontaine, René Otten, M. A. Wolfe +2
In order to enable semiconductor-based quantum computing with many qubits, issues like residual interqubit coupling and constraints from scalable control hardware need to be tackle…
