Optimization of a solid-state electron spin qubit using Gate Set Tomography

Understand

State of the art qubit systems are reaching the gate fidelities required for scalable quantum computation architectures.

• Further improvements in the fidelity of quantum gates demands characterization and benchmarking protocols that are efficient, reliable and extremely accurate.
• Ideally, a benchmarking protocol should also provide information on how to rectify residual errors.
• Gate Set Tomography (GST) is one such protocol designed to give detailed characterization of as-built qubits.
