Fast and High-Fidelity State Preparation and Measurement in Triple-Quantum-Dot Spin Qubits

We demonstrate rapid high-fidelity state preparation and measurement in exchange-only Si/SiGe triple-quantum-dot qubits. Fast measurement integration (980-ns) and initialization (approximately 300-ns) operations are performed with all-electrical baseband control. We emphasize a leakage-sensitive joi...
