Our latest work on gate-set evaluation metrics for closed-loop control has been published in npj Quantum Information. We use an ensemble of NV centers to compare different measures of the gate-sets performance for applications in closed-loop quantum optimal control. We demonstrate the relative trade-offs between these measures and show how to significantly enhance the gate-sets performance.
