High-Fidelity Entangling Gates for Quantum-Dot Hybrid Qubits Based on Exchange Interactions

27 Jan 2020 Yang Yuan-Chi Coppersmith S. N. Friesen Mark

Quantum dot hybrid qubits exploit an extended charge-noise sweet spot that suppresses dephasing and has enabled the experimental achievement of high-fidelity single-qubit gates. However, current proposals for two-qubit gates require tuning the qubits away from their sweet spots... (read more)
