Abstract: Highlights•A novel time-parallel multiple-shooting method for quantum optimal control.•Defined a generalized infidelity for intermediate non-unitary state matrices.•Estimating the roll-out infidelity using a time-parallel algorithm.•Efficient gradient calculations with an adjoint-based approach.•Up to 80x speedup in gradient evaluation using time-parallel execution.
