A parallel wrapper around GRAPE that enables ensemble optimal control optimisations.
This function handles systems with multiple control power levels, multiple resonance offsets, multistate transfers, and ensembles of drift Liouvillians.
waveform - control coefficients for each control operator, rad/s
fidelity - figure of merit for the overlap of the current state of the system and the desired state(s). When penalty methods are specified, fidelity is returned as an ar- ray separating the penalties from the simulation fidelity. gradient - gradient of the fidelity with respect to the control sequence. When penalty methods are specified, gradi- ent is returned as an array separating penalty gra- dients from the fidelity gradient. hessian - Hessian of the fidelity with respect to the control sequence. When penalty methods are specified, gradi- ent is returned as an array separating penalty Hes- sians from the fidelity Hessian.
