From: Enhancing quantum control by bootstrapping a quantum processor of 12 qubits
MQFC process for optimizing a control field. Starting from an initial guess, a shaped pulse is created from the pulse generator and then applied to the sample. The fidelity function f of the control pulse and its gradient g are directly measured on the quantum processor, where g is used for updating the control field till that sufficiently high fidelity f has been achieved
