A shooting technique yields smooth control pulses for quantum gates on spin qudits that are faster than GRAPE, with the advantage growing as system dimension increases, shown in numerical simulations inspired by single molecule magnets.
In all this article, we chose to compare execution times with 10(dim + 1) piece-wise amplitude steps for each controls, with dim being the dimension of the Hilbert space at hand

Implementation of a shooting technique for quantum optimal control on spin qudits
A shooting technique yields smooth control pulses for quantum gates on spin qudits that are faster than GRAPE, with the advantage growing as system dimension increases, shown in numerical simulations inspired by single molecule magnets.
