Robust and fast post-processing of single-shot spin qubit detection events with a neural network
Tom Struck, Javed Lindner, Arne Hollmann +4
Establishing low-error and fast detection methods for qubit readout is crucial for efficient quantum error correction. Here, we test neural networks to classify a collection of sin…

Low-frequency spin qubit detuning noise in highly purified Si/SiGe
Tom Struck, Arne Hollmann, Floyd Schauer +8
The manipulation fidelity of a single electron qubit gate-confined in a Si/SiGe quantum dot has recently been drastically improved by nuclear isotope purification. Here, we…

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…
